Australia's remote Macquarie Island research station will have a new home on higher ground to avoid increasing storm surges and elephant seals.
The sub-Antarctic base has been in operation for 70 years at the northern end of the World Heritage-listed island.
The federal government in 2016 announced $50 million toward the construction of a new station, with the Australian Antarctic Division on Thursday revealing it will be built slightly south.
The higher location was carefully chosen after two seasons of analysing weather, potential rising seas and storm surge frequency, AAD project manager Adrian Young said.
"The new site avoids intensive wildlife congregations, nesting areas and heritage artefacts, as well as the swampy ground nearby," he said.
"It's also outside the storm surge area and has good access for construction."
It will also have a lighter environmental footprint and impact on nesting penguins and an elephant seal colony, Mr Young said.
The project is in the design phase, with construction expected to be completed in 2021-22.
Some of the new station will overlap the existing one.
The AAD has launched a 360-degree online virtual tour, made up up of 1338 photos stitched together, to help designers and builders view the site from afar.
The Macquarie Island station, established in 1948 and about halfway between Tasmania and Antarctica, is occupied year-round with up to 25 people staying over the summer season.
