Federal Deputy Opposition Leader Julie Bishop said she believed Australians were ready for a change of government as she voted at the Cottesloe Civic Centre on Saturday morning.
Accompanied by Premier Colin Barnett, the federal member for Curtin was warmly greeted by voters lining up to have their say in the election.
Ms Bishop said she had spent the morning at a number of polling booths and had gained the sense that people were ready for change.
"I've heard from a number of my colleagues in the eastern states and they tell me there's a good reception, people are receptive to a change of government, there's good feedback about Tony Abbott, about our campaign, about our team and our policies," she said.
"So I'm hoping that we will be able to maintain that mood for change in Western Australia."
Despite a sense of trepidation, which she said accompanied every election, Ms Bishop was feeling confident but stopped short of predicting a victory for the coalition.
"I don't like to predict anything at this point," she said.
"I get the sense there is a strong mood for change...here in Curtin I'm feeling pretty good about the response I've had so far. The rain didn't dampen any spirits here this morning.
"After six years of Labor, people have been so bitterly disappointed with the chaos and dysfunction and are looking for certainty and stability and competence in government, and that's what Tony Abbott and the team can deliver."
There was some confusion in the polling room, with a slight delay in finding Ms Bishop's name in the electoral roll prompting a colourful exchange between the Premier and the Deputy Opposition Leader outside the polling room.
"I said my name is on the roll, trust me," Ms Bishop said.
"(If) you lose by one vote, you can't blame anyone else," Mr Barnett said with a laugh.
