Campaigning is drawing to a close before Saturday's general elections in Australia. Opinion polls suggest that the race will be the tightest in fifty years. The country's first female Prime Minister Julia Gillard is facing a strong challenge from the Conservative opposition leader Tony Abbot. Julia Gillard is using the last day of the campaign to mount a strident and negative attack on Tony Abbott, warning voters he is a risk to their future prosperity. But the Opposition has hit back at the Prime Minister, accusing her of being panic stricken. The two leaders have appeared almost non-stop on radio and television this morning in a last-ditch bid ahead of Saturday's poll.
