Floodwater levels are starting to drop across parts of central Queensland with locals enjoying the first sunshine in days.

However, Maryborough residents are anxiously watching the rising Mary River, which has already flooded dozens of properties.

Fraser Coast mayor Gerard O'Connell says the river has already surpassed its expected peak of 7 metres and could hit 8.5m.

About 20 homes and businesses as well as rural properties have been flooded in the region.

The suburb of Granville and the nearby hamlets of Poona, Boonooroo and Bidwill are isolated.

The mayor hopes the river peaks by mid-morning and starts to recede by noon.

"It's a beautiful fine day here today. I don't think it's raining anywhere in the catchment, so that should give us a bit of faith," he said.

Upstream at Gympie supplies are finally getting through to the town, which was hit by an 18.44m flood peak on Tuesday night.

Mayor Ron Dyne said Mary St, the main drag, has also been cleaned up.

"Everyone will feel better because the sun has come out. It may only be for a short time but it gives people confidence," he told AAP.

Gladstone mayor Gail Sellers says roads south and west of the city have been cut and there's plenty of water around but no homes are threatened.

Banana Shire Mayor Ron Carrige says the waters around Biloela are receding much more slowly than expected but he's thankful there's been no damage to any buildings.

However, here has been a lot of damage to rural properties.

"For a lot of farmers recovering from January it will be back to square one again," he told AAP.

"It's pretty disheartening.

Swollen rivers in the North Burnett region haven't affected any homes or properties but some bridges have been damaged.

Mayor Don Waugh is in a better mood with waters beginning to drop.

"The sky's blue, the sun's shining, the grass is green, you should come up and have a look at it," he joked.

But Mr Waugh warned there was a danger posed by snakes which have floated closer to towns on the floodwaters.

"It's very real," he said.

"Just in the town areas there are brown snakes. They are apparently pretty big ones too.

"People need to stay away from debris and long grass."
