Australian island struck by 7.3 magnitude earthquake sparking tsunami warning

An Australian island has seen an earthquake of 7.3 magnitude.

Macquarie Island, run by Tasmania since 1990, was put on a tsunami warning.

The quake was reported by the US Geological Survey at 8:49pm on Thursday near the island at a depth of 29.3km.

The island, halfway between Australia and New Zealand, is the permanent home of the Australian Antarctic Division.

It's also listed as a UNESCO World Heritage Site, holding the status since 1997.

Large colonies of penguins and seals call the island home.
