Regional radio posts, foreign news bureaus, flagship rural program Bush Telegraph and 400 jobs are among the victims of deep budget cuts at the ABC.
ABC managing director Mark Scott today revealed a raft of proposed changes to programming, operations and structures to offset $254 million in lost federal government funding over the next five years.
Close to 10% of the ABC's ongoing workforce face potential redundancy, including management.
"It's a sad day for all of us - no one takes any joy with the job cuts that we face," Mr Scott told ABC News 24.
"It's a very significant job cut, and those job cuts are going to have an impact right across the organisation."
Five regional radio posts - in Wagin (WA), Morwell (Vic), Gladstone (Qld), Port Augusta (SA) and Nowra (NSW) - will be shut down, as well the ABC's Adelaide television production studio.
Foreign bureaus will be restructured and a post opened in Beirut.
State editions of the ABC's 7.30 program will be axed and replaced with a national show on Fridays, while Lateline will be moved to a new fixed timeslot on ABC News 24.
ABC TV's sports coverage will also be scaled back, with the axing of state-based local sports coverage and outside broadcast vans decommissioned.
Flagged changes to radio include the axing of Radio National's rural program, Bush Telegraph, and fewer concert recordings for ABC Classic FM.
The $254 million cut is 4.6% of the ABC's budget and means it will now receive $5.2 billion over five years rather than $5.5 billion.
