MY KITCHEN Rules finalist Bree May might live in Adelaide, but she's an honorary Sunshine Coaster.

The mother, who is competing on the reality cooking show with friend Jessica Liebich, has her strongest supporters right here on the Coast.

Ms May's mum Sue Dalmeyer, who lives at Caloundra, is an interior designer, while her sister Dyani lives at Mount Coolum.

"My entire immediate family and a lot of my extended family live in Queensland," Ms May told the Daily.

"One sister lives in Coolum and another sister lives in Brisbane at North Lakes.

"They're obviously my biggest fans.

"While I was always filming (for the show) my children went up there for a couple of weeks to spend some time with my Mum and Dad.

"They love it up there."

Ms Dalmeyer described the show as an "emotional rollercoaster" for the family.

"We have been absolutely nervous wrecks," she said.

"It's been really hard to watch at certain times - especially when they've had problems - and we've gone to bed at night and we can't sleep."

Ms Dalmeyer said the team's struggles earlier in the contest came because they were homesick.

"Being away from their children, they were fretting really badly and they went right down into a hole," she said.

"But they just clawed themselves back up and now they've got back their confidence."

Ms May has been sworn to secrecy but Ms Dalmeyer would not be surprised if her daughter won.

"I said to her when she first started that I would not be surprised if she won it," Ms Dalmeyer said.

My Kitchen Rules airs on tomorrow at 6.30pm and Monday and the final on Tuesday at 7.30pm on Channel 7.
