Micro parties have emerged as the other big winner in the West Australian election, with the Legalise Cannabis WA party claiming two upper house seats.
The final count for the Legislative Council was completed on Tuesday, formalising Labor's commanding majority across both houses of parliament.
In addition to winning a remarkable 53 out of 59 lower house seats, Mark McGowan's Labor government has also claimed 22 upper house seats.
It is the first time Labor has won a majority in the Legislative Council.
Daylight Saving Party candidate Wilson Tucker was elected in the Mining and Pastoral region despite polling just 98 votes.
His victory was made possible by complex preference deals which have also catapulted Legalise Cannabis WA candidates to victories in the South West and East Metro regions.
Former Fremantle mayor Brad Pettitt was elected for the Greens in the South Metro region in an otherwise disastrous showing for the party.
The party has been reduced from four upper house MPs to one, with former party leader Alison Xamon among those to lose their seat.
Mr Tucker's election comes despite the fact he has spent the past three years living in the United States where he has a software engineering job.
Voters in his region are staunchly opposed to introducing daylight saving.
Mr Tucker told Perth radio 6PR he was planning to return to Australia and undergo quarantine as soon as possible.
The newly re-elected Labor government has promised to look into electoral reforms which could stop micro party candidates from gaming the system.
Parliament is expected to resume at the end of the month with the obliterated Liberals facing an enormous rebuilding task.
The party has been reduced to just two lower house MPs, with the Nationals set to claim official opposition status.
