The local shire of the Daly River region in the Northern Territory says crocodiles will pose the biggest problem with expected flooding of the river system.
Residents are preparing for flooding as the water from heavy rain in the Katherine region makes its way into the river system.
The deluge washed away the Territory’s major rail and road routes to Darwin two days ago.
The shire’s Andrew McTaggert says the river is expected to rise quickly within the next 24 hours.
“At this stage the crocs are the biggest problem that will arise out of this,” he predicted.
“The last floods we had this year, I think they caught three or four crocs just in and around the community here where the kids go and have a swim.
“So that’s the biggest thing. They take all the dogs and sooner or later they’ll take a child.”
Mr McTaggert says the river will rise quickly when it arrives and could reach 13.5 metres.
“People in low-lying houses will be evacuated,” he added.
The Daly River Mango Farm’s Gary Higgins says he has been preparing since yesterday.
“We’ve got accommodation and a licensed bistro so all of that [has been] packed up and we lift that to a height of 14.5 to 15 metres.
There are also concerns the raging river could damage construction works on a local causeway and the Daly River bridge.
