BRISBANE, March 9 - Eight teachers and 72 Year 6 students from The Willows State School are trapped at the Echo Creek adventure park after roads between Cairns and Townsville were swamped by 200-250mm of rain over the past 24 hours. 

A Queensland Police spokesman said the group was safe and in constant contact with authorities. 

Emergency services won't attempt to rescue them due to safety risks, but are preparing to provide them with food supplies.

The spokesman said a father of one of the children had driven through floodwaters and attempted to paddle a canoe to the group on Thursday, but had later turned back.

In a message to parents on Thursday, the school's principal, Helen McCullough, said staying at the site was the safest option. 

"We know that parents would like to talk with students, however at this stage we need the telephone communications open for the team to contact the camp," she wrote on the school's Facebook page. 

"Students and staff are continuing to do activities and there is plenty of food supplies available."

With rain continuing in the already waterlogged region, police have warned residents about major flooding, especially in Ingham and Halifax as the Herbert River rises.

Ingham has already been cut in two by water, with the Herbert yet to peak, and it could go higher than the town's last major flood in 2009.

Hinchinbrook Shire Council Mayor Ramon Jayo has warned residents the town could be cut off for some days safety must be taken seriously.

Ingham school kids were sent home early on Thursday, as locals stripped supermarket shelves of essential supplies.

Flood waters have crept across suburban streets and into backyards, lapping at the front steps of homes.

"I had a look out the window at about four o'clock and there was nothing in the yard that I could see," Ingham resident Felix Scerri told the ABC.

"I've just woken up in the last few minutes and there is water everywhere I can see."

At least 14 schools and one child care centre in north and far north Queensland remain closed on Friday.

Extra swift water rescue crews have been sent to the region and authorities are planning to deliver supplies to towns that lost road access some days ago.

Major flood warnings remain in place for the Herbert, Tully, Murray, North Johnstone, Mulgrave, Russell and Flinders rivers. Moderate and minor flood warnings are in place for many other rivers in the region.

Authorities are pleading with motorists not to cross flooded roads.

On Thursday, Cairns tradie Sam Greenwood staged a heroic rescue of a motorist caught in a car that was floating away on the Gillies Highway.

The electrician dived into the water and swam to the vehicle, finding a man inside struggling to keep his head above the water.
