Ah, the old chestnut reappears....
OK, my understanding about early races, based on recent discussions on various forums is as follows:
There was some kind of "Yamaha BMX Gold Cup Series" held in shopping centres around 1975. The evidence of this is robw's post above and also an interview of Mick W, where he mentioned this at Roselands in Sydney. It appears that this "series" was in fact a one-off promotion and regular racing did not continue thereafter.
We have all seen the "Tally Valley" letter (too many bloody times) but as DB18 says, NO ONE has ever come forward with any tangible or credible evidence that the track existed or indeed whether any organised racing too place. So as far as I am concerned, it was something someone tried to start, but probably never got anywhere with.
The earliest fully documented, photographed, videoed race facility in Australia was Busaco Road in North Ryde (now called Macquarie Park). This appeared on "Simon Townsend's Wonder World" on Channel 10, as well as appearing in Australasian Dirt Bike Magazine and of course several of the regular forum members also raced there. Racing commenced in the first quarter of 1977 as I understand it and several race meetings were held there in late 1977 and the first quarter of 1978.
I also understand that the Windsor Track in Brisbane started ALMOST as early Busaco Road, probably only a matter of weeks in the timing.
So to be fair to all involved, it's probably truest to say that regular organised BMX racing started at about the same time in NSW and QLD, at North Ryde and Windsor respectively.
