A 3.9 magnitude earthquake has rumbled a remote part of the Great Barrier Reef off far north Queensland.

The quake struck the tip of Maori Reef about 50km northeast of Russel Heads, south of Cairns, about 12.17am on Sunday 

It was about 10km deep, says Geoscience Australia, with 78 people reporting they felt the tremor.

About 16 earthquakes have been reported off the state’s far north coast over the last two decades, the agency said.
