The federal opposition is pushing the nation's public broadcasters into its election pitch to voters, promising to provide greater funding certainty for the ABC and SBS if elected.

Labor has seized on the latest review of the ABC's operations, launched by the Senate's Communications Committee and chaired by Liberal senator Andrew Bragg, to accuse the Coalition of chipping away at the nation's public broadcasters.

ABC chair Ita Buttrose has described the review as an act of "political interference designed to intimidate" the organisation.

The ABC and SBS currently receive funding in three-year blocks, which the federal opposition argued left the broadcasters vulnerable to the electoral cycle.

"We will grant them the certainty that they require to make investments, to go forward in a way that maximises the output that they have and the services they provide," Labor leader Anthony Albanese said.

"The attacks on our public broadcasters must stop, and under this government what we've seen is a constant undermining at the very time in which we know that the public broadcaster is our most trusted news source."

Last year, the ABC axed hundreds of jobs, citing a funding cut of almost $84 million. 

Labor promised to restore that funding to the ABC but did not make any broader financial commitments for the two organisations it described as "pillars of our democracy".

The Coalition has long argued ABC funding has increased year on year — a position which has been disputed by the organisation itself and the government's political opponents. 

The opposition has also recycled its pledge to move the headquarters of SBS to western Sydney, putting the multicultural broadcaster in one of the most ethnically diverse parts of the country.

Shadow Communications Minister Michelle Rowland said a Labor government would commit to a feasibility study to determine the best location.

"It's about working in partnership with local governments, it's about delivering for local communities — not only in terms of the media, but also in terms of community space, of ensuring that local organisations have places where they can produce content and have their faces and voices seen and heard."

Khal Asfour, the Mayor of Canterbury Bankstown, said the local community would welcome staff into the fold, rather than dealing with "people blowing in from Artarmon", where SBS is currently based.
