New Member for Mallee Anne Webster is set for a pay rise 17 days after starting her job.
The current base salary for federal parliamentarians is $207,100 but will increase to $211,000 as of July 1.
Dr Webster will be able to claim $14,000 per annum from the Remuneration Tribunal because her electorate is larger than 5000 square kilometres in size (81,962 sq km).
The incoming MP said as she understood it, the salary she received would be backdated to election day, May 18. On Thursday, Dr Webster said she would not be able to start her work representing Mallee until after the declaration of the poll on Saturday, July 15.
"I've volunteered my life for the past 12 years doing the work I've been doing (with her charity Zoe Support), so money is not the focus of what I've been doing or what I will be doing," she said. "I think it's a negative thing to be focusing on at the moment. I'd be surprised if people actually thought about it.
"My estimation in terms of the cost of the campaign for me personally has been around the $40,000 mark. I made that choice and willingly put my hand to the plow and I'm going to continue doing that."
Dr Webster said she had yet to make decisions about flights and other expenses allowable within parliamentary salaries.
A report by the tribunal from March 8 stipulates members can receive an allowance to cover the costs of each night staying in commercial accommodation as part of their job. In both Horsham and Mildura, the amount claimable is $379 a night.
Politicians can also claim an extra $19,500 per annum if they have no private vehicle. Dr Webster said she would not be claiming this expense, but taking over former Mallee member Andrew Broad's car.
Mr Broad announced he would not contest the 2019 election in December, after it emerged the married MP had dinner with a woman he met online while in Hong Kong. It later emerged he used taxpayers' money for part of the overseas trip.
Mr Broad served two full terms in parliament, his final day being April 11. Under Department of Finance rules, he does not qualify for a parliamentary pension, as he did not serve 12 or more years or on four separate occasions.
Instead, he will receive a lump sum payment which will be preserved in a superannuation fund or an approved deposit fund until he reaches the preservation age - generally 55 - and retires from the workforce altogether.
A department spokeswoman said it did not provide information on former politicians' individual benefits.
