Pearce's incumbent MP and the nation's attorney-general Christian Porter has maintained his confidence, despite a tough 3.6 per cent margin stacked against him and rivals eyeing off his top spot.
On April 11, Australian Prime Minister Scott Morrision visited Governor General Sir Peter Cosgrove to ask for parliament to be dissolved and the writs issued for an election.
After months of speculation, this writ gave the authority for the 2019 federal election to be announced and set out for May 18.
The nation will elect 151 MPs (one from each seat) to the lower house and 33 senators (six per state and two per territory) to the upper house. Senators have six-year terms, so a regular election - such as this one - means only half of the Senate is up for re-election.
Since Mr Morrision's announcement, the Avon Valley's federal MP Mr Porter has appeared in nation-wide headlines for holding shaky ground and being "the underdog" ahead of polling day.
While candidates from smaller parties have reared their heads in recent weeks, Mr Porter's main rival lies in police officer Kim Travers.
Ms Travers has been endorsed as Labor's federal candidate for the seat and has promoted herself as a stable option that would advocate for the region's toughest issues.
Raised by her grandparents in the country town of Merredin, she has claimed to have a strong connection to the electorate.
Ms Travers has spent almost 30 years in the force and was even promoted to the Superintendent overseeing the WA Police Custodial Services and Mental Health Division as well as the delivery of the two-year Mental Health Co-Response Trial.
Mr Porter recently visited the region to rally much-needed votes and to officially annouce a $1.5 million investment into a new Headspace in Northam, as part of his party's mental health and youth suicide prevention strategy.
The commitment was first revealed on April 9, which was swifty followed by a promise by Ms Travers for $3 million to a new Headspace facility if federal Labor was voted in.
She had joined shadow assistant mental health minister Deborah O'Neill to outline the region's need for the centre.
In an interview with The Advocate on Friday, Mr Porter said while he knew he had a steep battle ahead it was one he believed he could achieve.
"I'm the underdog," he said.
"I'm facing down Bill Shorten's candidate [and] the union's GetUp!
"They'll spend a million dollars trying to knock me off but we've produced great results as a government and I've produced great results as a local member for my local community."
Over the next four weeks, constituents can expect to see Mr Porter preaching his party's plan of boosting the nation's "economic management" and relieving the pressure on middle-income earners through tax cuts and hand-outs.
Mr Porter listed mental health, cost of living pressures and infrastructure woes as the areas he would place the most amount of time on throughout the campaign, as he said they were important issues in the region.
"We've managed to deliver record spending on health, on education, on infrastructure," he said.
"We've managed to do that by bringing the country back to surplus and we go into this election campaign without a single dollar of extra taxes. I'll be reminding people in the Avon Valley and elsewhere [of] that."
The Greens have announced their Pearce candidate as teacher Eugene Marshall. Mr Marshall has vocalised rising power bills and a lack of financial support to the education sector as issues worth campaigning for.
He has offered himself as an alternative to the major parties, which he claims have "created an economy that only works for corporations, instead of doing what's best for our community".
The Nationals have put forward Steve Blyth as their candidate. Mr Blyth has labelled himself as community focused and "not a career politician".
He has also touted his work on various environmental and education boards as giving him experience to deal with the health system and crime-related issues.
Pauline Hanson's One Nation party are also taking a punt in Pearce, after appointing Sandra (Sandy) Old as their candidate. Ms Old grew up in the eastern Wheatbelt and has five children and six grandchildren. Having worked in worked in small business for over 35 years, Ms Old labelled one of her focuses as cutting red tape slugging companies, stating that "government is making it harder and harder to do business".
On March 1, Clive Palmer's United Australia Party endorsed nine WA candidates, which included Robert Forster.
A former East Ward councillor for the Shire of Mundaring, Mr Forster has belonged to multiple local organisations and committees including recreational committees and a ratepayers association.
Australian Christians have endorsed physiotherapist Magdaleen Strauss. Ms Strauss has been living in the Pearce region for the past eight years and said she understood the area's challenges regarding schooling, development, growth and healthcare.
The Australia People's Party have selected surveyor and small business owner Stephen Piper as its candidate. Mr Piper has expressed concerns over "the steady influx of migrants and the pressure it has caused on our schools, hospitals and public services".
