The location of an earthquake that struck off the Queensland coast on Friday morning.
A magnitude 4 quake was recorded at 6.45am on Friday, about 120 kilometres east of Fraser Island at a depth of 10km.
It was felt by people as far south as Brisbane but no damage was reported.
Geoscience Australia say the tremor is the 13th aftershock in the area following a 5.4 magnitude quake in late July.
Seismologist Marco Maldoni says plate activity could be ongoing but is not unusual.
"You get a large one but they tend to die off ... that's usually the pattern, so we assume it is part of that," he said.
