The World Heritage-listed Macquarie Island has been declared free of pests after a near-seven-year campaign to eradicate it of rats, rabbits and mice.
Macquarie Island lies 1,500 kilometres south-east off Tasmania in the sub-Antarctic.
In 2007, the Australian and Tasmanian governments jointly funded a $25 million project to eradicate all rabbits, rats and mice from the 13,000-hectare island.
A baiting program was undertaken, before hunters and their dogs were brought in to eradicate any surviving animals.
A monitoring program since then has not detected any pests for the past two years and the eradication program has been declared a success.
