The Australian V8 Supercars round in Perth has been scrapped by the sport's governing body, with officials labelling the circuit "third world".
The organisers have reinstated the City of Ipswich 300 at Queensland Raceway, but dropped the event at Barbagallo Raceway.
The Western Australian circuit was under trouble with V8 Supercars keen to have the facilities upgraded before committing to stay there.
The V8 Supercar championship begins next week in Abu Dhabi followed by the Desert 400 in Bahrain.
A nine-week break punctuates the season, lasting from mid-July to mid-September.
The Hamilton round is from April 16th to 18th.
