Independent Indi candidate Helen Haines will push for the ABC to have the indexation freeze on its funding lifted and ensure it stays publicly-funded if elected.
Responding to reports in the Sydney Morning Herald this week, Dr Haines said she was "deeply concerned" it could be privatised.
"I'm deeply concerned by the call from the Institute of Public Affairs, which is a think-tank that has the ear of the Liberal and National parties, to privatize the ABC," she said.
"I will fight to maintain not only adequate funding, but also the independence of the ABC so it's not a political toy to be played with by major parties.
"I call upon the Liberal and National candidates to step forward with me and guarantee like I am they will fight for the maintenance of the ABC and re-establishment of full funding to the ABC, and that they would fight like I will to ensure it is never privatised."
