Leo Geoghegan’s Holden 48-215 from Frank Hamm’s Jaguar Mk5, Bathurst, Easter 1959…

I’m not sure if this is the parade lap described below or a race but the presence of the sportscar in amongst the touring cars suggests the former.

The stunning series of photographs are uber-rare ones from the inside of Conrod Straight, the cars have just cleared Forrests Elbow and are winding up in top gear. The kid standing on the fence is Rick Meyer, his father took these wonderful rare photos trackside, ‘locals’ photographs.

The Easter meeting was the Gold Star round traditionally- there are a huge number of past, current and future top liners or champions amongst the entry list. ‘Currents’ include Stan Jones, Doug Whiteford, Ross Jenson, Curley Brydon, Jack Myers, Jack Murray and David McKay. ‘Future stars’ are Len Lukey, Alec Mildren and Bill Patterson- Gold Star winners in 1959, 1960 and 1961 respectively, Lionel Ayers, Glynn Scott, Arnold Glass, Frank Matich, Ron Phillips, Ron Hodgson, Doug Chivas, Leo Geoghegan, John French, Des West, Max Volkers, Brian Foley, Ian Geoghegan, Brian Muir and ‘Ken’ Bartlett- no doubt Kevin Bartlett learned the value of clean, clear hand-writing on entry forms when he perused the race program at the circuit!

The photo below is from the same spot and shows reigning World Champ Jack Brabham on the 2 October 1960 weekend when the local boy returned to Australia having retained his F1 drivers title, to win the ‘Craven A International’ from a classy field of locals.

The Cooper T51 Climax leads the similar white-coloured machine of 1961 Australian Gold Star Champion, Bill Patterson. Patterson was second in the race with Bib Stillwell, also T51 equipped in third- he is probably that flash of red car behind Patto.

The photo below is again Geoghegan who is about to take, perhaps, Barry Gurdon’s Austin on the run down Conrod, or is it a Triumph Herald? By this stage Leo’s car is very quick and much modified- light weight, it has a Repco Hi-Power cylinder head and multiple SU carbs, is fitted with an MG TC gearbox, slippery diff and disc front brakes.

The introduction of the Australian Touring Car Championship from 1 January 1960 run to Appendix J regulations would reign-in the ‘costs out of hand’ development of touring cars without in any way constraining the appeal of tin-top racing to either spectators or owner-drivers.

Beautiful picture of the Les Wheeler funded, Gordon Stewart designed and built Stewart MG…

Believe it or not this very advanced car was concepted and constructed in the early fifties around a tubular steel spaceframe chassis, MG TC engine and brakes. With a Bob Baker built body, modified in the nose here, it first raced at Mount Druitt in 1955.

(R Meyer)

The engine was 1350cc in capacity and fitted with a Laystall crank and locally made rods. By the time the car appeared lots of serious stuff from Europe was racing locally so it missed the boat a bit as a potential ‘outright’ contender but its 1957 Gordon Stewart driven 142 mph made it the fastest TC speed ever over Bathurst’s Flying One-Eighth!

Here, Dick Willis says the car is supercharged ‘B-Series’ BMC powered, still with Gordon at the wheel. This car is extant and a wonderful feature article, such is its conceptual design and execution, for another time.

(D Willis)

A bit more from Dick Willis, here the Stewart MG crew- ‘Ecurie Cinque’ at Mount Druitt probably in 1958. ‘Jim Robson (at right) of Silverdale fame was a technical writer for Riley (Nuffield) before the war writing workshop manuals etc. After the war he emigrated to Australia and soon struck up a friendship with the like, Nuffield minded, Gordon Stewart- Jim was one of the team who developed the Stewart MG…’

Paul Newby explains that Horst Kwech built the RM Spyder whilst working at Regional Motors in Cooma- New South Wales sub-alpine country, hence the ‘RM’. It comprised a Buchanan bodied upside-down Singer chassis powered by a Repco Hi-Power headed Holden ‘Grey’ six-cylinder engine and still exists in Canberra.

‘Joisus Harry and the boys look after me pretty well’ is perhaps the thought going through Peter Brock’s mind…

Harry and the Boys are the Holden Dealer Team- Harry Firth, Ian Tate, Bruce Nowacki and others who built and prepared the various Holdens that Australian Touring Car Greats, Peter Brock and Colin Bond raced.

The Birrana 272 Ford ANF2 car Peter is looking after at Hume Weir in 1973 was a Father and Son operation between Geoff and Peter Brock.

This wasn’t new to the touring car ace mind you- the Austin A30 Holden Sports Sedan which thrust the lad from Diamond Creek to fame was run in just that manner but by 1973 he had been a works driver for four years with all of the cossetting- and expectations which goes with it.

Brock has that ‘where the hell is Tatey’ look about him!? Mind you, he may have just spotted a pretty young filly at the burger stand and doing that instantaneous, nano-second process of visual assesssment we all do.

This is another of my whacky-dacky articles in that it started as a mid-week quickie but grew like topsy into a feature as I chased a few tangents- so its not as cohesive as some of my efforts. Its a bit of this and a bit of that, without being a whole lot of any one thing! Bare with me all the same.

I’ve written about this important car- ‘272-002’ and Brocky’s time with it before.

The car is significant in the pantheon of Birranas in that that it was the first monocoque chassis Tony Alcock and Malcolm Ramsay built, as well as the first of a very successful run of Formula 2 and Formula 3 cars constructed by Birrana between 1972 and 1974- noting that production spluttered along into 1978 with a couple of additional cars built in the interim.

In 1972-3 ‘272-002’ was raced by Ramsay, 1971 AF2 Champ Henk Woelders once, Leo Geoghegan and Brock before passing into Bernie Zampatti’s hands in Perth- he still has it, so rather a nice jigger to own in every respect.

Some of the additional photographs of the car were taken in the Sandown paddock during the weekend Malcolm Ramsay contested the ‘Victorian Trophy’ Gold Star round in April, i’m wondering if this was the car’s race debut? Frank Matich won the race in his Matich A50 Repco, with Ramsay seventh- FM took the Gold Star that year, his only Australian Drivers Championship in a couple of decades at the pointy end of Australian motor racing in both sports cars and single-seaters.

For most of the year Malcolm raced the car in South Australia and Victoria- in addition to the Gold Star round at Sandown there was a ‘Repco (fiftieth) Birthday Series’ of five rounds at Calder contested by F3, F2 and F5000 cars- won by Kevin Bartlett’s Lola T300 Chev

Tony Alcock built the first Birrana- the Formula Ford F71-1 initially raced by John Goss and then David Mingay in the garage behind his house in the Sydney suburbs. By the time the later F72 FF’s were constructed he was in partnership with Malcolm Ramsay back in his native Adelaide.

Ramsay had previously raced Elfins and Alcock worked for Garrie Cooper both before and after a sojurn to Europe working for McLaren, Cooper, Cosworth and others- both were mates of Garrie, so in a way it must have felt strange competing with the much respected outfit from Conmurra Road Edwardstown.

Ramsey- is that him sitting on the tub? and 272 at cold, windy Calder during 1972- possibly the August meeting (oldracephotos.com.au/Hammond)

Mind you, the story is that Malcolm approached Garrie to build him a car with some design features he wanted, the ever accommodating Cooper was fully committed with the build of the 620 and MR5 series of cars at the time so really didn’t have the capacity to do a ‘one off’. So Mal decided to do it himself and approached Tony who was at a loose end at the time.

The 272 was an utterly conventional racing car of the period but what was different from the Elfin 600- which had pretty much ruled the small-bore racing car roost in Australia since its 1968 Singapore GP win with Cooper at the wheel, was that the Birrana had a monocoque chassis whereas the 600- a winner in FF, F3, F2 and ANF1 guises was a spaceframe.

The 272 was beautifully built and quick out of the box- its performance when driven by Malcolm and ‘Dame Nellie Melba’ Geoghegan when Leo- the 1970 Gold Star Champion returned from short-lived single-seater retirement to drive the car later in 1972- and Birrana Australian Formula 2 Championship wins in 1973 (273) and 1974 (274). For the record, Birrana national F2 titles were also taken by Geoff Brabham (274) in 1975 and Graeme Crawford (273) in 1976.

Leo first raced the 272 in the Hordern Trophy Gold Star round at Warwick Farm in November only completing 3 laps before having gear lever problems. He raced the car again in the final Repco Birthday Series round at Calder in December and was convinced of the Birrana’s potential so signed to drive one of two works ‘273’ cars- the other raced by Ramsay in 1973.

The 273 took Alcock’s concepts further, the 274 further again with sales and wins aplenty- the full history of Birrana is for another time.

At the end of the 1972 season Birrana sold the car to Brock- who made it available for Malcolm Ramsay to race in the opening round of the 1973 championship at Hume Weir whilst Peter attended to Holden Dealer Team commitments.

Malcolm handed the car to Leo who had broken valve spring problems with his 273 Hart motor throughout the weekend including raceday. Geoghegan took a great and somewhat lucky win from the rear of the grid when Tony Stewart’s leading 273 had overheating dramas and had to reduce his pace- the plucky, quick Victorian was second and Chas Talbot, Elfin 600E Ford third.

Brock raced the 272 for several more meetings before he too acquired a 273. Brock’s too short single-seater/Birrana sojurn is told here; https://primotipo.com/2018/05/07/brocks-birrana/ , with some Birrana history here; https://primotipo.com/2016/04/29/birrana-cars-and-the-1973-singapore-gp/

The 272 had a locally built 1.6 litre Lotus-Ford injected twin-cam engine- the Hart 416B variant de-rigeur in Australia from 1973 when all of the top-guns used these motors excluding Peter Brock.

Hewlands ubiquitous 5 speed FT200 gearbox was specified with lower wishbone bottom, top link and radius rod suspension at the front and single upper link, two lower links and twin radius rods deployed at the rear. Roll bars were used of course with cast Birrana uprights, wheels and steering rack finishing off a very nice package.

Evolution of the 272 to 273 clear in this shot inclusive of period-typical ‘Tyrrell type’ enveloping nose.

Marque experts rate the 273 the pick of the Birranas with the 274 said to be not really a quicker car- as proved by the pace of Buesselmann’s car when driven by Bob Muir for the Browns in 1974 fitted with 274 nose and rear wing.

Geoghegan crushed the opposition in 1973- demonstrating amazing reliability, he finished all seven of the championships rounds, winning six of them- one in the 272, the balance in his 273. In a busy season, Geoghegan and Ramsay also raced the cars in Asia- this tour is covered in one of the articles linked above.

Afterthoughts…

Bob Skelton and the Bowin P6.

An interesting thing looking back at this F2 season is the performance of 1972 ‘Formula Ford Driver to Europe’ (DTE) winner Bob Skelton and his spaceframe chassis Birrana P6 Ford-Hart.

He was, despite being a far less experienced open-wheeler pilot than Leo who had been racing Tasman 2.5’s since 1966, and was racing wings and slicks for the first time- right up Geoghegan’s clacker on raw pace if not finishing record that season in a brand new, unsorted car. Two second placings from four of the seven rounds he finished was his best.

Let’s look a bit closer in terms of raw speed- at Hume Weir both Leo and Bob didn’t record a time- Tony Stewart started from pole on 45.4 seconds with no race times disclosed.

At Oran Park Geoghegan was on pole 42.3 secs, with BS right behind him on 42.5, Brock 44.2.

At Amaroo LG pole 48.7, BS again in second slot with 48.9, PB on 51.9- the last round of the series Brock contested.

At Surfers the cars raced within the Gold Star Glynn Scott Memorial Trophy F5000 race- Skelton bagged the F2 ‘pole’ with 1:9.5 from Leo on 1:10.4 with BS a tenth quicker in the race- the first occasion that happened that season.

Chris Farrell, Dolphin 732 Ford (Brabham BT36 copy) and Enno Buesselmann Birrana 273 on row 2 with the distinctive #62 black Bowin P6 Hart of Bruce Allison on the right- to the left is Ian Fergusson’s Bowin P3 Ford. The #3 white 273 is Don Eubergang in the ex-Tony Stewart ‘273-007’- then an assortment of Elfin 600’s and a couple of Cheetah Toyota F3’s towards the rear- a very young John Bowe is in one the 600’s (ACY)

From Queensland the circus moved down South to Symmons Plains in Tasmania where Leo put the championship beyond doubt- both did 55.7 secs in practice. Skelton didn’t contest the final rounds in Adelaide or at Calder.

The conclusions to be drawn from the above are firstly that Skelton was a very quick driver- no shit Sherlock- he had won the DTE in 1972 apart from demonstrable pace in the sports and touring cars from whence he came. On raw pace the Bowin P6 was the equal of the Birrana 273 despite being brand new and untested prior to the seasons outset- and in the hands of a ‘wings and slicks’ novice.

It is a great shame Skelton’s single-seater career ended at this point, he deserved another crack at F2 or elevation to the F5000 Big League.

Bob got the babes, or TAA ‘hosties’ air- hostesses as they were before the days of political correctness!

Slumming it on Fairlanes are second placed John Leffler and third place-man Bob Beasley- all raced Bowin P4A’s (unattributed)

In fact Skello’s ‘P6-119-72’ was the very first P6 built by John Joyce, completed, according to Bowin records, on 8 September 1972.

After winning the DTE in his trusty P4 Bowin Skelton raced the P6 once or twice in Oz to Formula Ford specifications- the P6 was an FF/F3/F2/Formula Atlantic spec car, four of the latter were exported to Canada in 1973/5, before shipping it to the UK and contesting the Snetterton Formula Ford Festival or ‘World Championship’.

He raced in the UK together with fellow Australians Larry Perkins (1971 DTE winner), John Leffler (1973 DTE winner) Buzz Buzaglo and Peter Finlay- the latter duo were at the time living in the UK and were ‘jets’ in British/Euro Formula Ford. How the Aussies fared is covered in this feature on Buzz I did yonks ago;

After shipment of the P6 back to Sydney the Bowin lads removed all the Formula Ford clobber- ‘Kent’ 1600 motor, Mk9 Hewland, brakes, wheels etc and added Hart 416B, FT200, wheels and calipers and wings and the rest and had the car ready- just, for the first 1973 F2 round at Hume Weir.

Hey presto, now I’m an F2! ‘P6-119-72’ in F2 guise with a nice shot of Skletons trick, schmick alloy, short-stroke Hart 416B twin-cam, circuit unknown (MRA)

These days the beautiful, radical P6/P8 Bowins with their progressive or ‘variable rate’ suspension are somewhat maligned on social media- it really is time I attack Bowin as a subject and address the facts armed with statistics in relation to the P6/P8- favourite racing cars of mine!

The colour photo above is Skelton’s P6 in front of Brock’s 273 at Oran Park during the ANF2 Championship round on 5 August- Geoghegan won from Brock and Skelton. Peter’s second place was the best of his two 1973 championship appearances, the final one was at Amaroo Park, also in outer Sydney, a fortnight later where he was sixth.

After that Brock ceased racing the 273- as quickly as he started it- the lure of touring cars was too great, Holden weren’t happy for Brock to race a Ford engined car and no doubt the self-running nature of the program was no fun- and by then not what was required to win in F2.

Mark Fogarty quoted Brock as saying ‘Brock was disillusioned by the formula…in 1972 F2 meant a simple chassis and twin-cam engine, but in 1973 monocoque chassis and supertrick Hart motors were the rule if you wanted to be competitive’. ‘Brock, in between HDT commitments, struggled on…until it became apparent that he was banging his head against the wall without a Hart…’

PB was second in the ’73 Oran Park round, here in his new Birrana 273- unsponsored. Odd the lack of support for the 1972 Bathurst winner (ACY)

Peter Brock and single-seaters.

The opening photograph in this article aroused plenty of Facebook chatter about Brock’s prowess as an open-wheeler driver- the fact is of course we can never be definitive about Peter’s capabilities because he simply didn’t stick at it for long enough to make a determination.

He had good equipment in both the 272 and 273 chassis but the cars were not, as noted above, fitted with the Ford-Hart 416B engine. Good for about 205 bhp, these motors were 15-20 bhp, depending upon accounts, more powerful than the best of the local twin-cams.

Most of the quicks in 1973 had them including Geoghegan, Ramsay, Buesselmann, Stewart, Skelton and Bruce Allison (Bowin P6- a sixth and a fourth Bruce’s best in a car he loathed- the 274 he raced in 1974 was much more to his taste and his results reflected it!) Winter (Mildren Yellow Submarine).

What we do know is that Brock was quick in anything and everything- in machines as diverse as the Austin A30 Holden, Touring Cars of god knows how many number from Holden Monaro GTS350 to V8 Supercars, rally and rallycross cars, Bob Jane’s 600 bhp plus Chevy Monza Sports Sedan to the Group C Porsche 956 Prototype he shared with Larry Perkins at Silverstone and Le Mans in 1984. In all of these cars and disciplines Brock was a winner or at least very competitive.

By all accounts- and so many of us watched him for four decades, so we all have a view- Brock was a versatile, adaptable, mechanically sympathetic, consistently fast and aggressive but thoughtful, analytical racer of elite international level and standing.

That does not mean he would have been an ace in single-seaters, but on balance, my ‘I reckon’ is that he would have been at least the equal of the best Oz resident open-wheeler guys had he focused in part or exclusively in the rarefied end of the sport…

Let the debate begin!

Tailpiece 2…Leo G and Birrana the dominant 1973/4 F2 combo…

(AMY)

I’ve taken a few twists and turns in this article but let’s not lose track of Leo’s superb driving in 1973- Birrana gave him a brilliantly designed, built and prepared car that year and in 1974which he put to very good effect.

A shame was that he didn’t switch into F5000 after his 1970 Gold Star win aboard a Lotus 59B Waggott- Lord knows we needed a few more cars on the grid, but it was great, having read so much about Leo before I first went to a race meeting, to be able too see so many of his F2 races in 1973 and 1974! He was ‘the goods’.

RIP Leo Geoghegan.

Finito…

Geoff Brabham gets the jump from Grace Bros Racing team-mate Andrew Miedecke and Alfie Costanzo at the Hume Weir, Australian National F2 round on 15 June 1975…

Birrana 274 Ford Hart, Rennmax BN7 Ford Hart and Birrana 274 again- Costanzo won that day but Geoff won the series.

In the black helmet at far right on the second row is Ray Winter in the Mildren ‘Yellow Submarine’ still a winner seven years after it first raced in Frank Gardner’s hands in the summer of ’69 Tasman Series.

The high water mark of Australian National Formula 2 racing (1.6 litre, DOHC, 2 valve- which effectively mandated the Lotus Ford twin-cam engine- the ducks guts version was the Hart 416B circa 205bhp injected variants) was in 1974 when an infusion of sponsorship dollars from shirt manufacturer Van Heusen resulted in an influx of drivers stepping up into the class and/or acquiring new cars.

Guys like Leo Geoghegan, Enno Buesselmann, Bruce Allison, Ken Shirvington, John Leffler, Chas Talbot, Wolfgang Prejawa with Sonny Rajah jetting in from Malaysia and Graeme Lawrence did a round or two from NZ. In some cases drivers ‘stepped down’ from F5000- Bob Muir, John Walker, Kevin Bartlett and Max Stewart to name a swag. For the sake of clarity Leo was an established ace- having finally won the Gold Star, the national drivers championship he deserved in 1970, he retired and then did a ‘Nellie Melba’ and returned to drive Malcolm Ramsay and Tony Alcock’s new Birrana 272 in mid-1972.

An absolute corker of a 1974 series was won by Leo in the ‘works’ Grace Bros sponsored Birrana 274 Ford-Hart in a closely fought battle with the Bob and Marj Brown owned Birrana 273 raced by Bob Muir and Leffler’s ‘tricky-dicky’, superb, variable rate suspension Bowin P8.

Sex on Wheels. John Leffler’s John Joyce designed Bowin P8 Ford-Hart at Sandown’s Dandy Road during the 1975 Tasman meeting, DNF suspension (B Keys)

Predictably in some ways the Van Heusen money ended up supporting ‘taxis’ in 1975 despite the great show put on by the F2’s in 1974. All the same, the 1975 championship was a good one given all the newish cars about.

Into late 1974 or early 1975 Costanzo bought Leo’s championship winning car- and in that ’75 season gave his career the shot in the arm it needed after running around in an old Elfin 100 Mono F2 for way too long. I think Alfie did travel to Italy seeking a drive in the late sixties, without success- imagine if he had popped his bum into the right car back then rather than a decade later at the end of the seventies when Alan Hamilton’s Porsche Cars Australia finally gave him the drive he deserved- the ex-VDS/Brown Lola T430 Chev F5000 and subsequently the McLaren M26 Chev and Tiga Formula Pacifics into the early eighties.

Brabham and Miedecke stepped up from Formula Ford- a Bowin P6F and Birrana F73 respectively, retaining their Grace Bros support which helped fund far more sophisticated and expensive cars than their FF’s. Geoff took the obvious choice in acquiring a Birrana 274- a low mileage, late build car from Neil Rear in WA whilst Andrew sought the ‘unfair advantage’ with a new Rennmax- the BN7 from Bob Brittan’s Sydney workshop.

In fact it wasn’t that edgy a choice really as his car was a refinement of Doug Heasman’s BN6 which hit the track about 12 months before- the speed of which was proven by Bob Muir in one or two races in the car before he got the Brown’s Birrana ride at Enno Buesselmann’s expense.

This photograph shows clearly the middle monocoque and front spaceframe sections of the ex-Miedecke BN7 recently (via R Bell)

Apropos the above- chassis front section (via R Bell)

The BN7 design was different to the paradigm of the era in having a monocoque centre-cockpit section and spaceframes both front and rear- the more usual approach was an ally mono from the front ending in a bulkhead aft of the drivers shoulders with an ‘A-frame’ at the rear to carry the engine and suspension.

Both the P8 Bowin and Rennmax were wedge nosed designs with side radiators whereas the Birranas and Elfins (works 622 as raced by Walker and 630) followed the ‘Tyrrell’ bluff nosed approach with a front radiator.

In a year of strong competition between Brabham, Costanzo and Miedecke Geoff took the title with three wins at Amaroo, Symmons and Phillip Island from Alfie with two wins- Hume Weir and Calder and Andrew, who won the first Calder round in May. Arguably the quickest of the trio was Costanzo but reliability was a little lacking on both his and Miedecke’s part.

With my new drivers licence I no longer had to rely on my reluctant dad to cart me around to race meetings- I saw the Calder, Sandown and Phillip Island rounds that season and well recall a chat with Geoff and Peter Nightingale, his mechanic/engine builder, after the final ‘Island round in late November which Brabs won in fine style.

He had his ‘tail up’ in his modest way and was looking forward to taking on the world in Europe.

Doug Heasman, Rennmax BN6 Ford from Peter Macrow, Cheetah Mk6 Toyota, Hume Weir, date uncertain (M Bishop)

Interest was added to the series with lady racer Sue Ransom doing some events in Leffo’s Bowin P8 Ford/Hart- I pissed myself with laughter watching him pop her Willans six-pointer on at Calder, he was far more judicious with the crutch straps than he would have been with a fella. In those days the two lady-quicks were Ransom and Christine Cole/Gibson, I always thought it a shame Sue didn’t race the Bowin for longer than she did. Leffler himself did a round or two in Paul England’s Brabham BT36/Dolphin in amongst his Bowin P8 Chev F5000 commitments- the Brabham/Dolphin was also raced a couple of times by Tony Stewart- a talent lost.

Other drivers who added colour were Ken Shirvington, Chris Farrell, Enno Buesselmann, Doug MacArthur in the Lola T360 Bartlett and Lawrence had ‘guested in’ the year before when it was imported and owned by Glenn Abbey- and Ray Winter still pluggin’ away in The Yellow Sub, albeit substantially modified by Mawer Engineering.

Brian Shead, Cheetah Mk5 Toyota ANF3- Mk5 the prettiest and one of the most successful Cheetahs of all- amazing what Shead produced from that little ‘shop in Mordialloc (M Bishop)

The quicker of the 135bhp ANF3 cars (1.3 litre, SOHC or pushrod engines on carbs) could always give an average driven 205bhp F2 a run for its money, dudes like the two Brians- Shead and Sampson, Paul King, Peter Macrow and Dean Hosking to name several who extracted all these little cars had to give.

(M Bishop)

I’ve no idea who the ace felling a ‘pine plantation’ at Hume Weir is, I’m intrigued to know? Ditto the car.

(M Bishop)

What about the career trajectory of the 1975 F2 protagonists you ask?

Miedecke did another F2 year in the BN7 in 1976, Costanzo acquired a Lola T332 F5000 and was immediately quick in it against the established 5 litre aces whilst Brabham headed off to Europe for a couple of Ralt RT1 Toyota F3 seasons before launching his pro-career in the US.

Geoff’s chassis, ex-Neil Rear was ‘274-018’, it was then bought by Ray Winter to replace the Sub but if memory serves he had a huge accident in it, Lakeside maybe? Now in the Holmes family collection (oldracephotos.com.au)
