35rd Annual Speed Week Lake Gairdner South Australia Monday 3rd March to Saturday 8th March 2025 The DLRA conducts its annual Speed Week at Lake Gairdner in South Australia. It's straight line speed on "the big white dyno", as fast as you can go on a salt lake in the remote Australian outback. There is no setting like it anywhere in the world, it is a truly unique event in a spectacular location. There is an amazing range of cars, motorcycles and trucks dating from the turn of the century to modern day. Spectators are welcome, but you need to be pretty much self sufficient.
