From another thread: David Koch, breakfast anchor for 2 decades on Seven Australia, is to retire after his final edition on 9/6. A new host has been appointed and will debut the following Monday:

That's big news but good innings for Kochie. I would imagine it'll be the host of Weekend Sunrise who takes over.

Well... the Mail is being told it won't be Matt Doran (who is the Weekend Sunrise host), but rather 7 Sport host (and former Olympian) Matt Shirvington, who has already filled-in for him in multiple occasions (including during the recent summer break).

As for Kochie, he's focusing on his other business ventures, including his media marketing agency Pinstripe Media, his partnership on business streaming network ausbiz, and especially as GM of AFL squad Port Adelaide Football Club.
