Vote counting is set to continue just over a week after the federal election, as winning MPs meet over the next few days to decide Labor side ministers and coalition party leaders.
Labor needs 76 seats to secure a majority in the lower house of federal parliament, with the party sitting on 75, according to the Australian Election Commission website.

A fourth seat is also considered tight by some experts – the Victorian seat of Macnamara.
