About 25,000 people have been told to evacuate as a cyclone carrying winds of up to 275km/h (170 mph) moves towards the Queensland coast.

Cyclone Debbie has intensified into a Category 4 system and is due to make landfall early on Tuesday local time.

Some people have refused to leave despite warnings the destructive core could be as wide as 100km (62 miles).

Queensland Premier Annastacia Palaszczuk said the storm would rival the devastating Cyclone Yasi in 2011.

Late on Monday, Ms Palaszczuk urged 25,000 residents in low-lying areas of Mackay to immediately find safer ground. More than 5,000 other Queenslanders were already evacuating their homes.

"The time for people to move is now," she said.

A state on edge

In its latest update , Australia's Bureau of Meteorology said the cyclone could "intensify further" as it moved towards the Queensland coast.

It is expected to make landfall sometime after 07:00 on Tuesday (20:00 GMT Monday) anywhere in a 265km zone from Townsville to Proserpine.

"That is the uncertainty of cyclones," said Bureau of Meteorology regional director Bruce Gunn.

Authorities warned the cyclone could coincide with high tide, which is expected to peak at 3.2m. The storm surge could add an additional 4m, Ms Palaszczuk said.

She said this would bring dangerous risk of flooding, especially around Mackay.

"I am just pleading to everyone, please, listen to authorities," she said. "I do, you must as well. This is about your safety, it is about the safety of your family and the safety of your children.''

Police Commissioner Ian Stewart said the weather contributed to the death of a woman in a car crash.

Queensland authorities have closed 102 schools, 81 early childhood education centres and two ports.

All flights have been cancelled at Townsville Airport and Mackay Airport.

Mr Stewart warned that emergency crews would not provide help during the storm's peak.

"[It] will get to an extent where all emergency services will not be able to respond to calls for assistance, because obviously, we have got to maintain the safety of our staff," he said.

Army ready to assist

Ms Palaszczuk said residents should be prepared for power outages.

"Now is the time to charge your phone," she said.

"These winds are going to be severe and we are going to see structural damage."

Prime Minister Malcolm Turnbull said the Australian Defence Force would help with the cyclone response.

"Time and time again, Australians show grace under pressure, bravery in the face of danger, and rally without a second thought to help each other," Mr Turnbull said in parliament.
