Labor has the potential to govern in its own right, as vote counting continues following the federal election.
On Sunday morning, official figures from the Australian Electoral Commission had Labor on 75 seats in the House of Representatives - one short of a majority.
The Liberal-National coalition was holding 51 seats.
Ten independents were on track for victory, joined on the cross bench by Mayo MP Rebekha Sharkie from the Centre Alliance and veteran Kennedy MP Bob Katter.
The AEC listed 13 seats where the two-candidate preferred vote was unavailable: Bradfield, Calare, Canberra, Cowper, Grey, Griffith, Hinkler, Macnamara, Melbourne, Richmond, Ryan and Sydney.
Three seats were formally listed as "close": Menzies, Moore and Lyons.
Labor picked up 52.4 per cent of the two-party preferred vote.
Incumbent MPs were trailing in 19 seats: Swan, Pearce, Tangney, Hasluck, Curtin (WA), Chisholm, Higgins, Kooyong, Goldstein, Deakin (Victoria), Wentworth, Reid, North Sydney, Robertson, Mackellar, Fowler and Bennelong (NSW), and Boothby and Sturt (SA).
The Senate results are yet to be finalised, but the most likely biggest losses will be veteran Queensland senator and One Nation leader Pauline Hanson and Liberal minister Zed Seselja in the ACT.
