The result of the Fisher by-election in South Australia remains too close to call.
The Liberal Party had been expected to win the seat, but Labor has polled strongly and leads on a two-party preferred basis.
It could be days until the result is known with about 7,000 postal votes to be counted on Tuesday.
About 24 per cent of people cast postal and pre-poll votes, which are likely to determine the result.
The Liberals need more than half of the postal and pre-poll votes to win the seat.
