Tropical Cyclone Alfred has been downgraded to a low after crossing the Gulf of Carpentaria in northern Australia.
Alfred was a category 1 cyclone, with winds of up to 95kph, when it crossed the coast between Borroloola and the Northern Territory/Queensland border around 12.30am Queensland time.
The Bureau of Meteorology says it has since weakened into a tropical low.
Warnings for heavy rains that could lead to flooding over the next 24 hours and damaging winds remain in place for the eastern Carpentaria district.
"The system is expected to move inland today and produce heavy rainfall over the far eastern Carpentaria district before heading west over the Carpentaria district later today and on Wednesday," the BOM said on Tuesday.
Damaging winds up to 100kph are also expected.
About 74 people from the Garawa community living on the edge of Borroloola have already moved to higher ground, and authorities are warning all residents to stay indoors.
"The community I can say does have enough supplies for up to five days," NT Police, Fire and Emergency Services executive director Jennifer Reilly said.
A nearby airstrip is still open and can deliver more food depending on weather conditions.
Ms Reilly said emergency workers moved the evacuees in flood boats as a precautionary measure on Sunday.
The town of around 1000 people has been completely cut off and Ms Reilly urged drivers not to take risks on flooded roads, which will be closed for the next few days.
