Anthony Albanese says climate change is a critical national security issue, as Australia backed a plan at the COP27 climate conference to promote "green" shipping.
As delegates attend the annual climate summit in Cairo, the prime minister said Australia had an obligation to engage with Pacific countries on climate change.
"Climate change is a national security issue. That is something that is recognised by the United States, it's something that's recognised by our other partners, and indeed, our allies," he told parliament on Tuesday.
