The tremor hit at a depth of 10 kilometres some 29 kilometres from the island, which lies in the Pacific Ocean about half-way between Australia and Antarctica, the US Geological Survey said.
"We have been in touch with the base and they did feel it, but only slightly. They're all fine and there is no damage," an Australian Antarctic Division spokeswoman told AFP.
No tsunami warning was issued.
Macquarie Island, which is 34 kilometres long and just five kilometres wide, hosts the permanent Antarctic base on a narrow, windswept strip of land.
