SUPPORT for the Abbott Government has fallen to a five-month low, after the continued parliamentary expenses scandal led to Bronwyn Bishop's resignation as Speaker.
The latest Newspoll released on Monday showed Labor led the Coalition 54% to 46% on the key two-party preferred measure.
While the drop in voter support for the government was just one point since the last poll three weeks ago, it was the worst result for the Coalition since March.
Labor frontbencher Mark Dreyfus said on ABC Radio on Monday the result reflected Prime Minister Tony Abbott's defence of Ms Bishop over several weeks since the expenses scandal began.
However, government Parliamentary Secretary for Foreign Affairs, Steven Ciobo, told Sky News that "none of us get particularly excited by polls that go up and down".
Both major parties have support on primary votes at 39%, with Labor's unchanged from the previous poll and Coalition support falling one point.
