Tropical Cyclone Marcia barrelled through the northeastern state of Queensland Friday at the highest-rated category five, ripping apart houses, uprooting trees and bringing down power lines.
The severe system hit hours after category four Tropical Cyclone Lam slammed into the Northern Territory, causing extensive damage to remote Aboriginal communities near Elcho Island, some 500 kilometres east of the territory's capital Darwin.
Both cyclones have since ceased, but the Bureau of Meteorology warned of further flooding, heavy rains, damaging winds and dangerous surf in southeast Queensland and northern New South Wales state.
"It has been absolutely horrific what these people have gone through."

Despite the destruction, authorities have so far not received reports of serious injuries, missing people, or deaths.
"We are very happy to say still... That no person has been seriously injured and we certainly have no reports of anyone missing at this stage so we hope that that will continue," state disaster coordinator Steve Gollschewski said.
"Yeppoon has suffered the brunt of the cyclone and it is going to take a lot longer for power to be restored," she said, adding that some 60,000 people were without electricity. Water and sewage systems were also affected.
Power was slowly being returned in the towns but could take a few days to be fully restored, Palaszczuk added.
Queensland's fire and emergency services said 200 homes in Yeppoon and 340 in Rockhampton were damaged or flooded. Gollschewski said so far 40 severely damaged structures had been found in the two towns.
