Dry Lake Racers Australia 29th Annual Speed Week
Held on Lake Gairdner South Australia, ~1600km from Canberra with a map here. The nearest camp with fuel, water, showers and toilets is Mt Ive Station 38km from the lake. You need to bring everything else. Bush camping is conditional as is riding on the lake (never mind the irreversible damage to your bike).
Check and read the DLRA webpage for details here https://www.dlra.org.au/2019.htm.
Racing is weather dependent and requires a hot dry pre-summer. Serious crashes and other admin issues can cause a delay to or cancellation of racing, so plan an extended trip though the scenic Gawler Rangers and districts as a backup.
