Angry sections of the Western Australian Liberal party are pushing to launch a fresh attempt for the state to secede, in what members are calling "WAxit" – a nod towards Britain's vote to leave the European Union.

The Liberal Party's division of Brand has proposed the idea, which comes in response to long-held unhappiness in the state with GST distribution.

Western Australians voted to self-govern in 1933 but the move was overruled.

The WAxit idea is one of 25 motions to be put to this weekend's state conference, potentially embarrassing Prime Minister Malcolm Turnbull who is due to address the gathering.

The motions, provided to Fairfax Media, show the Brand division calling for the party to establish a high-level committee of three ex-MPs and three State Council members.
