The Australian Electoral Commission has formally declared the result in the first of 151 seats up for grabs at the May 21 federal election.
The NSW seat of Eden-Monaro was finalised on Thursday morning, with Labor's Kristy McBain holding it with a margin of just over 8 per cent.
The AEC plans to formally declare the seats of Cook, held by former prime minister Scott Morrison, and Macquarie, held by Labor's Susan Templeman, on Friday morning.
It is expected Labor will hold 77 seats in the lower house, with the coalition holding 58, the Greens four and 12 others on the crossbench.
The Senate election result is yet to be finalised.
The 47th parliament is due to open on July 26.
