Darwin residents were shaken awake in the early hours of this morning by tremors from an earthquake in the Banda Sea near Indonesia.

• Residents felt the ground shaking for around a minute just before 4:00am CST
• Geoscience Australia says the magnitude-7.3 quake hit hundreds of kilometres away in the Banda Sea
• There have been no reports of damage, GA says indications are of "moderate to light" impact

There have been no reports of damage or injuries.

Geoscience Australia (GA) said the magnitude-7.3 quake hit north of Timor-Leste, in the southern Banda Sea.

The Bureau of Meteorology said the earthquake happened shortly before 4am local time or 5:30am AEDT.

It said there was no tsunami threat to the Australian mainland, islands or territories.

GA senior seismologist Hadi Ghasemi said seismic waves travelled hundreds of kilometres to rattle the Top End capital.

"Our modelling and also the first reports all suggest a moderate to light level of ground shaking, " he said.

"We don't expect any damage to well-built structures."
