Nationals MPs and senators are gathering in Canberra today to settle their Coalition agreement wish-list as Malcolm Turnbull's new government starts to take shape.

The Coalition's victories in the seats of Flynn and Capricornia were confirmed last night, giving it 76 seats and allowing it to govern in its own right.

The ABC's election computer says the Coalition will retain both central Queensland seats, currently held by Liberal National Party MPs Ken O'Dowd and Michelle Landry.

The Coalition had been trailing in both seats, but postal votes flowed strongly in its favour, allowing it to overtake the ALP.

The West Australian seat of Cowan has been officially called for Labor, but the other victories mean the Coalition will not be forced to rely on Lower House crossbenchers for support.

Ms Landry, who described watching the vote count as tense, said she was pleased her victory helped get the Coalition over the line.

"I think a lot of people want us to succeed, that's why they've given us a second chance," she said.

Despite the numbers swinging in his favour, Mr O'Dowd said he was not ready to call victory yet.

"It's been up and down. I went to bed on Saturday night thinking I'd won by 2.5 per cent. I woke up on Sunday night [and] I was down 2 per cent," he said.

"This week and last week has been a gradual pull back of about 2,200 votes. I want to be really sure of it before I make any bold statements like saying I've won."

The Government also hopes it can win the seat of Herbert in north Queensland, although both sides agree the seat is too close to call for now.

Labor leading in remaining two seats

But its parliamentary majority will still be slim — the Coalition will struggle to win more than 77 seats in the Lower House.

Labor is pulling away from the Coalition in the seat of Hindmarsh in Adelaide.

The ALP has also claimed victory in the Perth seat of Cowan for counter-terrorism expert Anne Aly, who replaces three-term Liberal MP Luke Simpkins.

Dr Aly said it was a relief to claim victory after days of vote counting.

"I think it's going to settle in over the next few hours. It has been a long wait and it has been a very emotional ride," she said.

"It's a very proud moment for me, but also a very humble moment for me."

Dr Aly said Coalition attacks over a letter she wrote recommending a hardline Islamic preacher take part in her deradicalisation program may have helped her campaign.

"I do believe it did backfire. It certainly didn't lose me any votes."

Mr Turnbull declared victory on Sunday before returning to Canberra, where he received a briefing from Department of the Prime Minister and Cabinet boss Martin Parkinson.
