3AW breakfast presenter John Burns has apologised on-air after revealing his licence was disqualified over a second drink-driving offence.
On Thursday morning's Ross and John show, Burns interrupted the program to confess he'd recorded a blood alcohol reading of 0.061 during a roadside breath test last year.
The breath test occurred on the way home from hosting a children's charity benefit for cerebral palsy at the Riversdale Golf Club, Burns said.
"I'm pretty embarrassed about it and pretty ashamed too," he said.
The presenter said he'd been drinking wine at the event, but was "convinced that the amount I'd consumed would ensure I was under the limit".
A prior reading of 0.051 in the past ten years meant he now has to attend court and "let a judge decide what happens to my licence from here".
"I'm ashamed of this," Burns told listeners.
"I know that in our position we are expected to set an example, and given we report on the indiscretions of others, I leave myself open to pretty harsh criticism - and deservedly so."
As well as a contrite message to the show's followers, Burns offered an apology to his 3AW co-host Ross Stevenson for any negative publicity the offence might cause the program.
"I apologise for letting everybody down," he said.
Stephen Beers, 3AW Operations Director, said he was "extremely disappointed" in Burns.
"3AW supports all efforts of Victoria Police and the TAC to improve road safety... To have one of our presenters exceed the limit is unacceptable," he said in a statement.
He said the station would await the outcome of Burns' court appearance - at this point set for March - before taking any "further action".
Burns and Stevenson remain Melbourne's top rating breakfast radio show, with a commanding 20.1 per cent of the morning audience as of last year's final ratings survey.
