Civil Defence confirmed there is no tsunami threat to New Zealand.
Parts of Darwin's central business district have been evacuated as a precaution, according to ABC News. Residents have reported feeling a strong tremor, however no injuries or damage in Darwin have been reported.
"Everything was rocking... I was leaning back in my chair and I thought I was going to fall off," a Darwin resident posted to Twitter.
The quake struck at 2:53pm at a depth of 208 kilometres. It was felt in parts of Indonesia and in East Timor's capital Dili.
The earthquake was preceeded by a smaller, 20 kilometre-deep quake just minutes earlier. Reports differ as to whether the first tremblor was 5.1 or 6.1 magnitude.
Initial USGS estimates measured the larger quake as magnitude 7.5.
More to come.
