Australians are set to head to the polls this weekend to vote in a general election.

The latest opinion polls suggest Julia Gillard, the prime minister, could win by a narrow margin over opposition leader Tony Abbott's conservative coalition in Saturday's vote.

Both leaders have been talking tough on immigration, making a crackdown on asylum-seekers a key election issue.
