Australia risks ceding its influence in Antarctica to nations such as Russia and China because drastic cuts to scientific research are eroding its credibility in the region, respected scientists say.

They include the Australian Academy of Science, comprising more than 500 of the nation’s leading scientists, which has warned of Australia’s diminishing ability to address its Antarctic interests including its geopolitical claim, sustainable fishing in the Southern Ocean, climate change research and international Antarctic governance.

Australia has sovereignty over 42 per cent of Antarctica – almost six million square kilometres. It has traditionally played a commanding role in the affairs of the continent, largely due to its infrastructure assets and capability.

In a submission to a joint parliamentary probe into Australia’s Antarctic territory, the academy said the effectiveness of the nation’s investment “continues to decline”.
