WA has an election on March 8. So they can't do it until mid April at the earliest, now. They need to allow six weeks campaign time leading up to an election.

They'll probably see how the wind is blowing in WA before they announce. I predict early May.

At the moment, there are 3 (yes, three) Liberal members in the State parliament in WA. They'll obviously get more in March, but how many more is anyone's guess.

I just looked up when Easter is, since I know they usually prefer to avoid public holidays during the latter part of the campaign period. It's very late next year. 20 Apr. So with Easter plus ANZAC Day I predict 12 April if WA goes well for Labor, and 17 May (the last possible day for a half Senate election) otherwise. Neither ideal because of early overlap with WA or the public holidays, but reasonably clear space for the campaign.
