Large parts of southern Australia have been rocked by a massive 6.0 magnitude quake on Wednesday morning.
Geoscience Australia has said the tremor occurred in the Mansfield region in Victoria around 9.15am at a depth of 10km.
There are reports it was felt in Victoria as well as Tasmania, the ACT and New South Wales.
Some residents have reported feeling their homes shake for around 10 seconds.
There have already been reports of some building damage in Victoria in particular as a result of the quake.
Prime Minister Scott Morrison addressed the media in New York after learning of the quake and said the federal government was available to provide support if needed.
“At this stage we have had no reports of serious injuries or worse and that is very good news,” Mr Morrison said.
“It can be a very, very disturbing event for an earthquake of this nature.
“They are very rare events in Australia and as a result, I’m sure people would have been quite distressed and disturbed by that, particularly in the most immediate area affected.
“The agencies at a state government level are there responding and of course the federal government will provide the support that is necessary and will be in touch further with the Premier, I suspect, through the night.”
