Men appear to be switching their political allegiance to Labor for the first time in the five and a half years since Tony Abbott became the Liberal leader.

Labor Party support from men has climbed to a high of 38 per cent, now equal to the 38 per cent of men who back the coalition, according to analysis of Newspolls conducted for News Corp Australia in the first three months of 2015.

The analysis reveals the coalition's male support level is at its lowest point since Malcolm Turnbull was leader in 2009, and down 10 points since the 2013 election.

Labor support from women, meanwhile, outstripped the coalition, reaching 40 per cent for the first time since March 2010, when Kevin Rudd was prime minister.

The coalition's support among women is 37 per cent.

The analysis, based on Newspoll surveys of 4667 voters in the March quarter, also shows Mr Abbott's satisfaction among men and women has fallen below 30 per cent for the first time.

Opposition Leader Bill Shorten's satisfaction among men and women was 37 per cent, roughly 10 points higher than Mr Abbott.

Meanwhile, a separate Newspoll in WA shows the Labor Party has recorded its first Newspoll lead since 2008.

According to the poll, Labor leads Premier Colin Barnett's Liberal-National government 52 per cent to 48 per cent on a two-party basis.
