About 150 people have been evacuated from the Indigenous community of Beswick, east of Katherine in the Northern Territory, after the flooding Waterhouse River inundated the lower part of town.
Evacuees have spent the past two nights in the local school.
Mal Fox, from the Roper Gulf Shire, said water had gone through about six homes, but the damage was expected to be minimal.
"We evacuated everyone on Sunday up to the new suburb to the school and we were cut off from the bottom suburb," Mr Fox said.
"There was still some people that wouldn't move from the bottom suburb to the new suburb and didn't want to leave their pets or anything."
Mr Fox said everyone was safe but there would be a big clean-up ahead once waters receded.
"Yeah, a big couple of days ahead cleaning up," he said.
"Making sure everyone's right and making sure the power and water is right and we'll be back on track soon.
"Not too much damage done, thank God."
