Former ABC Managing Director Michelle Guthrie is taking legal action against the public broadcaster.
Fairfax Media reports she has filed a dispute in the Fair Work Commission against the ABC, although it is not yet clear which provisions of the Fair Work Act will form the basis of her claim.
Following her dismissal last month Guthrie hinted at legal action.
“While my contract permits the board to terminate my appointment without cause and with immediate effect, I believe there is no justification for the board to trigger that termination clause,” she said at the time.
“At no point have any issues been raised with me about the transformation being undertaken, the Investing in Audiences strategy, and my effectiveness in delivering against that strategy.”
An ABC spokesman also confirmed Ms Guthrie had commenced legal action but would not comment further, saying: “The details of the claim are not a matter of public record.”
