Key areas of the Warmun community remain at risk of flooding again this wet season, despite a $75 million campaign to rebuild on higher ground.
Hundreds of people had to be evacuated about 18 months ago when record rainfall flooded the community.
Seventy-six houses have been rebuilt but some buildings like Disability House were refurbished in the flood prone low-lying areas.
Community CEO Ralph Addis says those in the flood plain will be protected in future by better emergency plans and building materials.
"If there is a flood to that level that the damage to the buildings will be less," he said.
"They've been built in say flood-proof materials which while there'll be some damage there won't be anything like what we had last time and there'll be emergency management planning around how to make sure people are safe."
He says low-lying areas will be watched closely.
"The main facility that's a key issue for us is the Disability House where there's three or four disabled people and staff that live there," he said.
"That's been refurbished where it is which did go under, so that's going to be the key focus in the event that there's a flood."
