FARRER MP Sussan Ley has queried why her main election challenger, independent Kevin Mack, has been preferenced higher than Labor by the Greens.
Ms Ley tweeted a photo of Mr Mack under a "Please Stop Adani" sign and suggested it was a clincher to getting Greens preferences which came soon after the independent's declaration he would back the Coalition in the event of a hung parliament due to him being a "conservative right" candidate.
"It would suggest they believe Mr Mack's climate change policies are preferred to Labor's," Ms Ley said.
"Most of my constituents don't like Labor's climate change policies, let alone the Greens.
"Most of my constituents understand that the Labor agenda on climate removes water from irrigated agriculture communities and if that is the platform Mr Mack is running on because that is where his financial backing is coming from, there are serious questions to answer."
Farrer Greens candidate Dean Moss explained the reason why they preferenced Mr Mack ahead of Labor.
"The reason we decided to put Kevin ahead of Labor was because of his ongoing commitment to a Royal Commission into the Murray Darling Basin (Plan), his call for a federal anti-corruption commission and his record of good work in addressing climate action as Albury mayor," Mr Moss said.
"We know water is the most important issue in Farrer this election and Liberal, Labor and the National parties all have questions to answer in terms of management of the Murray Darling Basin."
The Greens preferenced Mr Mack third behind Sustainable Australia's Ross Hamilton with Labor fourth.
Mr Mack said Ms Ley was showing her desperation in retaining the seat.
"I've already indicated that in a hung parliament I would support the Liberal-National Party if they provided me with water and a Royal Commission, but now I'm in bed with the Greens am I?" he said.
"Which is it, Sussan?"
Ms Ley began the penultimate day of campaigning in Albury before embarking on a final run through river communities to Wentworth ahead of election day.
She released the findings of an aquatics survey she conducted after being approached by the Ovens and Murray Aquatics Action Group with its concerns about plans for the future.
"Something does need to happen so we have longer pool hours for the people of Albury," Ms Ley said.
"I, like all of them, want to see a state of the art aquatic facility for the next generation."
She said the Coalition's $4 million towards the Lavington Sportsground redevelopment was proof it backed major projects.
