Funding terms for the ABC and SBS would be extended in a bid to provide more financial certainty to the public broadcasters under a new Labor plan.
The federal opposition has pledged to extend the current funding cycles for the broadcasters from three year to five-year terms.
Opposition Leader Anthony Albanese said the proposal would move funding outside of the electoral cycle.
"We must ensure that Australia's instruments of nation building, democracy and culture remain strong now and into the future," Mr Albanese said in a statement.
"This includes independent public service media that holds power to account on behalf of the Australian people."
The current triennial funding for the ABC is due to end in 2022, during which time the coalition has been in power.
The funding announcement comes as the government has launched a Senate inquiry into the ABC's complaint handling process.
ABC chair Ita Buttrose has accused the government of political interference.
Journalist union the MEAA has estimated more than $780 million has been cut from the ABC since 2014.
Labor has previously pledged to reverse a funding cut of $83.7 million implemented by the government in the 2018 budget.
Mr Albanese said the extended funding terms would boost the independence of the ABC and SBS.
"A Labor government will review options for delivering a greater level of financial stability to the national broadcasters to safeguard against arbitrary ideological cuts and political interference," Mr Albanese said.
