More than 100 homes in western Queensland have been flooded and dozens of people airlifted to safety.

The Bureau of Meteorology has warned that river levels are likely to exceed flooding in 1974.

The red dirt town of Jundah, about 1300 kilometres from Brisbane with a population of just over 100 people, is a fresh epicentre for the emergency.

There are fears the floodwaters could wipe the town off the map.

“We have a community without power, without sewerage and we’ve got several evacuations where people have gone to higher ground at the golf course,” Crisafulli said.

Fears remain for hundreds of thousands of cattle and sheep who have become trapped in floodwaters.

Cyclone hits WA, Widespread rain over NSW

Elsewhere, Tropical Cyclone Dianne made landfall on the coast of Western Australia this morning at 5am.

The storm is set to weaken to below cyclone levels throughout the morning.

Dianne is set to pass the small town of Derby, about 200 kilometres northeast of Broome.

In NSW, the Bureau of Meterology has forecast heavy rain for much of the day around Sydney and in the state’s north.

The BoM predicts “Widespread rain and the chance of thunderstorms across most areas, contracting to the east and clearing the far west of the state during the day.”
