John Blackman has been dumped from 3AK Breakfast and insiders report more restructuring of support and news staff within the station.

Blackers’ on-air partner James Dunn will continue on breakfast with a new co-host and a new producer. Breakfast producer Mike Frazer was also axed.

This latest change makes five breakfast teams on the station in the past year. 3AK fell in the most recent ratings survey.
