Senior Liberals were talking up the chances of winning a bare majority of 76 seats.
But the Australian Electoral Commission figures at 10.45pm (AEST) were showing the coalition holding 71 seats and Labor 68, with one Green and four independents.
Six seats remained undetermined.
ABC modelling was showing the coalition holding 74 seats to Labor’s 66, with one Green, four independents and five seats in doubt - based on a two-party vote of 50.3-49.7 to Labor.
Labor was expected to pick up the coalition seats of Eden-Monaro, Macarthur, Macquarie, Lindsay in NSW, Longman and Herbert in Queensland, Bass, Braddon and Lyons in Tasmania, Solomon (Northern Territory), Hindmarsh (South Australia) and Burt (Western Australia).
The coalition was on track to pick up the Labor seat of Chisholm, while the Nick Xenophon Team claimed the Liberal seat of Mayo in SA.
