The ABC is facing "inevitable" job cuts and programming disruption if the Morrison government is returned to power, the national broadcaster's new managing director has warned.

In his first interview in the new job, David Anderson told Radio National's Patricia Karvelas that planning for two possible budget scenarios was at the top of his to-do list, after establishing a new leadership team.

One of those options is a budget in which the ABC's indexation funding is frozen for the next three years.

"If the Coalition is returned, then we have an $84 million budget reduction over the next three years," Mr Anderson said.
