Australia ordered thousands of people in its eastern regions to evacuate before Tropical Cyclone Alfred hits land on Saturday, as the storm brought heavy rain, huge waves and strong winds that cut off power, swamped beaches and shut airports.
Alfred's slow progress toward the coast fed concern it could bring a prolonged period of heavy rain and is expected to hit land as a Category 2 storm north of Brisbane, Australia's third-most populous city, the Bureau of Meteorology said.
"The evacuation centres are a last resort," Queensland Premier David Crisafulli told a news conference on Friday, adding that dozens had been opened.
"Have an evacuation plan if you are in one of those areas," he urged those in the cyclone's path, advising them to secure their homes before evacuating.
"If in doubt, go and stay with friends and families."
Wind gusts of more than 100 kph (62 mph) lashed the coastal regions of Queensland and New South Wales states overnight.
The storm moved slowly west 120 km (75 miles)from Brisbane and 85 kilometres (53 miles) from the tourist city Gold Coast, the weather bureau said.
It brought turmoil that snapped power links to more than 80,000 homes across the two states, electricity firms said, around half of them in Gold Coast.
Television images showed surfers riding the huge seas and people strolling near beaches, forcing officials to warn residents to stay indoors or prepare to evacuate.
"This isn't a time for sightseeing or for seeing what it's like to experience these conditions firsthand," said Prime Minister Anthony Albanese. "Please stay safe. Be sensible."
Albanese told reporters that 120 defence personnel would help emergency crews in rescue and relief efforts.
