The close-run general election has triggered a bipartisan push for the introduction electronic voting as five crucial seats remain undecided after more than a week of counting.

The Prime Minister, Malcolm Turnbull, and Opposition leader, Bill Shorten, both called for electronic voting to be considered for future ballots when the outcome of the election was formally resolved in favour of the Coalition on Sunday.

While conceding the Coalition's win, Mr Shorten expressed frustration at the slow progress of the count and said electronic voting was long overdue.

"We're a grown up democracy - it shouldn't be taking eight days to find out who won and who lost," he said. "We can't afford to let Australia drift for eight days after an election."
