The national five-round event features superbike, supersport, moto3/125GP, 200/300 production, unlimited, and 600cc and 1000cc club challenge racing.
Mike Jones currently leads the superbike class after he took the two race wins and overall win in round, two held in Queensland.
However, WA riders Adam Senior (currently 12th), Ashley Fleming (15th) and Tony Keogh (24th) will be looking to use their home track advantage to move up the ladder.
WA rider Thyron Van Vuuren finished round one of the supersport class at Phillip Island in fourth place but a crash in Queensland saw him drop to 11th.
Brayden Elliott currently leads the supersport class.
�I�m looking forward to the challenge of Barbagallo,� he said after round two.
�I have never ridden there before or seen the track, so it will definitely be a challenge but I�d say a lot of riders are going to be in the same boat.�
Michelle Marais, also from WA, is leading the production class.
�I am so happy we are riding at Barbagallo; it is my home track and the only track we have over there besides Collie, and I am pretty excited to go and ride on my home ground after this,� she said after round two.
Flying the flag for WA in the moto3/125GP class is Daniel Taylor, currently in 10th place.
