Karl Stefanovic congratulates Tracy Grimshaw on 40 years at Nine

Karl Stefanovic has shared a tribute to his Channel Nine stablemate Tracy Grimshaw as she celebrates a milestone 40 years with the broadcaster.

The Today host, 46, shared a throwback photo to Instagram on Tuesday from when they briefly hosted Nine’s breakfast show together in 2005.

In a lengthy caption, Karl congratulated the A Current Affair anchor, 61, on her stellar career and described her as a ‘guiding light’ and ‘master of our craft’.

‘It seems like last year… well, not quite,’ he wrote.

‘As a 30-year-old recruit out of LA I was given the unnerving honour of co-hosting the Today show. Among many other things Trace taught me how to prepare and interview in my own way,’ he added.

He went on to joke about all the skills Tracy had taught him. 

‘She taught me not to be needy because the business is tough. And she taught me how to drink and never show it the next day. Well two out of three ain’t bad,’ he said.

‘You are a master of our craft. And we are all fortunate to have you as a guiding light. Congrats on 40 years.’ 

Tracy started her career with Channel Nine in 1981 as a news reporter.

She hosted Today with Steve Liebmann from 1996 until 2005.

Karl replaced Steve in 2005 and soon after Tracy left to host A Current Affair and was replaced on Today by Jessica Rowe. 

Karl now co-hosts the show alongside Allison Langdon.
