Nola Marino will proudly serve the people of Forrest for another three years, after safely retaining the seat in the 2019 Federal Election.
With 77.26 per cent of votes counted, Ms Marino claimed 64.54 per cent of the two-candidate-preferred vote (49,701 votes) along with a 1.98 per cent swing.
Labor Party candidate Wayne Sanford scored 35.46 per cent of the vote (27,392).
Ms Marino picked up 40,700 first-preference votes, while Mr Sanford secured 16,532.
Greens WA candidate Nerilee Boshammer received 9,760 first-preference votes, ahead of Kalven Wayne Jamieson (Pauline Hanson's One Nation) with 4,430, Mark McCall (Shooters, Fishers, and Farmers) with 2,327, Dale Geoffrey Bromley (United Australia Party) with 1,328, Alexander Marsden (Independent) with 1,022, and Ian Bruce Molyneux (Western Australia Party) with 911.
The result marks Ms Marino's fifth consecutive win in 12 years.
"I think the result shows that people in the South West have confidence in our policies, our plans, and in Scott Morrison himself," she said. "When I came into this role, I wanted to become the best representative for the people and businesses in the region. That is still my top priority.
"The region's priorities are also my priorities, and I will keep working on those."
O'Connor voters have elected Liberal incumbent Rick Wilson for a third term, as the Coalition Government scores a shock-victory nationwide.
Polls had consistently shown Bill Shorten's Labor Party on course for victory, but Scott Morrison appears to have led the Coalition back into majority government.
In O'Connor, Mr Wilson won 64 per cent of the two-party preferred vote on a primary vote of 41.83 per cent, with most polling places returned.
Labor candidate Shelley Payne won 21.84 per cent of primary votes, an 0.92 per cent increase from the 2016 election.
The Nationals' candidate John Hassell suffered a swing against him of 5.78 per cent, finishing with just 12.55 per cent of primary votes.
One Nation candidate Dean Smith was narrowly ahead of Greens candidate Nelson Blake Gilmour, who's vote dropped by 2.32 points to finish on 8.05.
"It is an enormous honour and privilege to represent O'Connor in Canberra," Mr Wilson said.
"I would have expected that Esperance, being Shelley Payne's hometown, that she may have been able to swing some of the votes to her. But it appears that wasn't the case."
Both incumbents gave credit to Prime Minister Scott Morrison for staying focused on the economy and leading the Coalition to victory.
