In NSW & ACT they ARE ILLEGAL-having been an car club president/vice pres & competition organiser I know they illegal. We used to run a hill climb that started in NSW & the finishline was in the ACT, so i had to be familar with both state & territory rules.
In NSW if you have your numbers displayed whilst on the open road and you pass someone they can book you for racing
even though you might only be 60-80k's !! Not saying they will, but you've only got to meet a shi##y cop and he can Hammer you presuming he knows the legislation. The sam applies in the ACT, unless you're in a sanctioned event.
