The Barnett Government's loss in the Western Australian election shows conservative politics cannot match the campaigning commitment of the left, former Queensland premier Campbell Newman says.

Commenting on Sky, Mr Newman urged the Liberals and Nationals to find an answer to the union movement and activist groups such as Get Up which supported Labor.

"Time and time again in recent elections we've heard the same thing from people on our side of politics, which is the unions/Get Up ran this incredible campaign," Mr Newman said.

"When are the conservatives, the Liberals, the Nationals, going to get real and come up with a decent response?

"What do the conservatives do about this?"

Outgoing Western Australian Cabinet Minister Joe Francis told Mr Newman a union "scare campaign" was a factor in the Liberal loss in the west.

"Members of the union movement were flown into my seat of Jandakot on Saturday from Victoria. Prison officers … manned entire polling booths in my electorate," Mr Francis said.

Mr Newman said he experienced it himself when firefighters, doctors and nurses campaigned against him in Queensland, while the Federal Government had been forced to combat the "Mediscare" campaign last year.

"Resources, commitment and passion — frankly the Labor Party and the union movement have got it all over the Liberal Party and the National Party when it comes to campaigning in elections," Mr Newman said.

"They are absolutely kicking our butts."
