Federal Labor targets Lib, Nationals seats

Labor's win in Longman has the party targeting Liberal and Nationals seats where wages have stagnated and people feel left behind.

Watch out Nationals - Labor is coming for your seats.

The success of Labor's by-election campaign in Longman, where the Liberal National vote tanked, has the ALP targeting other low-income seats at the next federal election.

Incoming national Labor president Wayne Swan said voters were worried about growing inequality, especially in electorates where wages were flat.

"If you look at the median income in Longman and Braddon, it's $43,000," Mr Swan told Sky News on Monday.

"People on $43,000 don't even qualify for the government's measly $10 tax cuts."

Mr Swan the failure of trickle down economics was most keenly felt in those seats who felt left behind.

"There are plenty of electorates around Australia where those median incomes are around $43,000 - just like Longman - that can be won," Mr Swan said.

"Not just from the Liberals here, but from the Nationals as well.

"People out there have twigged to the fact that stagnating wages and growing inequality in Australia is a problem for their living standards."
