Inaugural MasterChef winner Julie Goodwin has been fined $600 and has lost her licence for six months after admitting to drink-driving.

Goodwin, 47, pleaded guilty in Gosford Local Court on Friday to driving with a mid-range prescribed concentration of alcohol (PCA) in April.

Magistrate Ron Maiden fined her $600 and disqualified her from holding a driver’s licence for six months.

In a post on Goodwin’s Facebook page in April, which is no longer available, the cook said she had been driving home from a “celebratory function” she had catered for when she was subjected to, and failed, a random breath test.

“Needless to say I accept full responsibility for this error in judgment, which I believe is completely out of character for me,” she said in the post.

Goodwin said in the post she wanted to offer a “heartfelt and unreserved apology” to her family, colleagues and the broader community.

“I am devastated that I have acted in a way so contrary to what I believe, to how I usually conduct myself, and to what I have taught my children,” she said.

“Many lessons will flow from this, and I will learn from each of them.”

Goodwin has written several cookbooks since winning the first season of MasterChef in 2009.

She starred in another reality program, I’m a Celebrity, Get Me Out ofHere, in 2015 and became a breakfast radio co-host on the Central Coast’s Star 104.5 that same year.
