UPDATE: The demountable buildings an excavator was trying to pull from Mary River floodwaters on Sunday are now floating down the river.
The Mary River is expected to peak about 6pm in excess of 10m and was at 9.7m about 7.30am on Monday morning.
EARLIER: DISABLED and elderly residents of Wallace Caravan Park and Motel were relocated to higher ground early on Sunday morning after water from the Mary River spread through the park.
Staff started to move demountable units and caravans to higher ground with a tractor, but were unable to move all the dwellings before they were flooded.
Later in the afternoon, Fraser Coast Councillor Daniel Sanderson organised a 12 tonne excavator to help move the demountable units to higher ground.
Wallace Caravan Park day manager Cherie Markham said they had been warned about the impending floods but were surprised just how quickly the river did rise.
She said they started to evacuate the park's residents at 7.30am and some were relocated to a nearby hotel.
Aged pensioner Heinz Quint said his motorhome was one that was inundated, and he rued the loss of perishable goods such as meat due to the lack of electricity.
