On a rainy morning at a community centre in Gumeracha, in the north of the sprawling Mayo electorate, MP-turned-candidate Rebekha Sharkie chats with a handful of voters.
She tells them about her long path to politics, her work for the Liberals, including for former state opposition leader Isobel Redmond, before her move into the youth sector and her position with federal government program Youth Connections.
It is at this point she crossed paths with then-senator Nick Xenophon.
After funding for the program was axed in the notorious federal budget of 2014/15, she reached out to politicians across the country for assistance and it came from the eccentric South Australian who helped her front a Senate select committee on the issue and later asked if she'd be interested in running for parliament.
With sitting Liberal in Mayo Jamie Briggs on the nose with voters, courtesy of his conduct on an overseas trip, it was an opportune time for Ms Sharkie who, with the help of Labor preferences, became the NXT's first lower house MP.
Now, two years after her historic win, she is lining up to do it all again, after falling foul of the dual citizenship saga that has ripped through federal parliament.
Ms Sharkie explains to those at the Gumeracha forum, as she has so regularly since her resignation, that she completed and sent off the relevant forms to renounce her entitlement to British citizenship before she nominated, but they were not processed until after the cut-off.
However, a High Court decision on the case of Labor senator Katy Gallagher confirmed she had little choice but to refer herself or resign.
With polls also in Braddon, Longman, Perth and Fremantle, July 28 will be a super Saturday of by-elections.
Now running as a member of the Centre Alliance, the rebadged NXT, Ms Sharkie has repeatedly apologised for sending voters back to the polls.
But she also likes to point out that the advantages of an electorate being represented by a crossbench MP are "immense".
She doesn't accept donations from big business or unions and votes only on the interests of the electorate.
"When you have a cross-bencher in, you instantly create a marginal seat, no matter what percentage they hold the seat by," she says.
"You also get somebody who is there entirely for the electorate, that's not wedded to party lines."
She cites the River Murray as an example of her advantage as an independent.
"We have seen stunning silences from the state Liberal government and the federal Liberal MPs for South Australia about the fact that David Littleproud, the Minister for Water, is going to the High Court to try and excuse himself from attending our royal commission," she said.
"I cannot believe that any member of parliament from South Australia, of any party, would not demand (it)."
Another environmental issue she's passionate about - and fiercely opposed to - is oil exploration in the Great Australian Bight, which incorporates some coastline in the electorate.
"I was so pleased when BP announced that they were getting out of the Bight," she said, adding she was equally disappointed when Statoil (Equinor) announced it was moving in."
Ms Sharkie said 10 councils had now come on board and agreed there should be no drilling in the Bight.
But it's been policy positions like these that have prompted some of her opponents to label her a Greens or Labor candidate by another name.
It's something she bristles at, arguing her voting record has more often aligned her with the coalition than the opposition.
Of equal concern, Ms Sharkie says, are some of the views of her Liberal opponent in Mayo, Georgina Downer, the daughter of long-time MP, foreign minister and party heavyweight Alexander Downer.
Ms Downer, she says, is part of a new wave of ultra-conservatism sweeping the Liberals.
"There's been a real pull away from what I would see as moderate, centre-of-the-road decision making, and I don't think that it's necessarily delivering good outcomes for Australia," she says.
The younger Downer is well-resourced but has faced backlash over her extended absence from the seat and because of the so-called "Downer Dynasty" sense of entitlement, be it perceived or real.
Ms Sharkie is hesitant to speak ill of her opponent - as Downer has also been - but does say the prospect of gaining another member of parliament closely aligned with former Prime Minister Tony Abbott is "monumentally catastrophic".
However, when it comes to some of Ms Downer's previous statements, she is more pointed.
In her work with the Institute of Public Affairs, Ms Downer voiced her support for the abolition of penalty rates and the minimum wage though she's told reporters those views were expressed as part of her employment.
"Somebody so willing to change their position or perhaps hide their position on a range of social issues, policy issues, you've got to question," Ms Sharkie says.
Ms Sharkie put a second mortgage on her home to fund her 2016 campaign and has promised this time letterboxes will not be bombarded with glossies because she simply doesn't have the funds.
Ms Sharkie says the electorate recognises it's a "David and Goliath campaign".
"They really like having a member that takes care and is focused on them, not using the seat as a landing place for a future political career."
A ReachTel/Australian Institute survey in June had her 62-38 on a two-party preferred basis.
But Ms Sharkie issues a caution: "You just can't be complacent in this game."
