An earthquake has rattled residents in the small Queensland town of Eidsvold, with tremors also felt in Brisbane, 430km to the south.
The 5.2 magnitude quake occurred about 2am (AEST) on Monday.
It was followed by an aftershock measuring 2.9 about 45 minutes later.
Callers to ABC radio have reported waking to rattling windows and shaking houses.
Dorothy, from Mundubbera just south of Eidsvold, said it was a strong tremor.
"The whole house shook, it just felt like the washing machine was off balance," she said.
"It shook and woke us up.
"We've been through it once before in the late 1980s. At that time the bed moved across the room but this time, well, it's not on wheels any more but it shook the whole house."
The quake was also felt as far north as Rockhampton, 322km away, and across the Sunshine Coast.
Authorities are warning of more aftershocks in coming days.
"We can't predict the magnitude or duration of the aftershocks but generally they become smaller and less frequent over time," seismologist Jonathon Bathgate, from Geoscience Australia, told the ABC.
Queensland Fire and Emergency Services said power appeared to be out in some areas.
People have described their experiences on the QFES Facebook page.
Danielle Bell Kawana, who was at the Sunshine Coast University Private Hospital, said the walls creaked.
"My bed was gently shaking," she said.
Amanda Wood, who lives at Buderim on the Sunshine Coast, said the shaking and rattling lasted for quite some time.
"I was woken to a rustling sound of the doors rattling. The bed shaking & the room vibrating. Lasted a couple of minutes. Very weird sensation!!" she wrote.
Nicola Addy, who lives 20 minutes north of Bundaberg, said her old house, which is on stilts, was rattling and shaking.
while Nambour resident Jeff Spencer said his pets went crazy.
"My cockatiel and dog went ballistic. WOW."
