Could not find more recent polls/results, SB, but what do you think of this February result for Western Australia:

SYDNEY (Reuters) - The rapid resurgence of nationalist politics in Australia was abruptly halted on Saturday after Pauline Hanson's One Nation party drew less than 5 percent of the vote and was set to win just one seat in a state poll.

The election in mineral-rich Western Australia was won convincingly by the center-left Labor party, leaving Hanson's right wing, anti-immigration party trailing far behind.

"This has certainly halted the sense of momentum building around One Nation that has been there since July last year," said Associate Professor Haydon Manning, a political scientist at Flinders University."

The deal appears to have back-fired, with Hanson losing some of her anti-establishment fervor and the state Liberals putting off their center-right base.
