The ABC agreed to pay former managing director Michelle Guthrie $730,000 to drop a court action over her dismissal from the public broadcaster late last year.

Ms Guthrie and the ABC reached the resolution last week after Ms Guthrie filed an adverse action in the Federal Court over claims her dismissal was in retaliation for raising complaints against former chair Justin Milne.

The payment of $730,000 is in addition to a $911,000 payout she received when she was fired halfway through her five-year contract, meaning she will receive a total of $1.64 million following her acrimonious departure from the broadcaster.
