Australia election: Millions head to polls

Australians have begun voting in a general election, with opposition leader Tony Abbott's Liberal-National coalition aiming to bring to an end six years of Labor government.

Opinion polls suggest Kevin Rudd, who returned as prime minister three months ago, is trailing his opponent.

The rivals are split on how to tackle Australia's budget deficit, but both have pledged tough action to stop asylum seekers arriving by boat.
