Australia has put $3.5 million towards supporting the international nuclear regulator as Pacific leaders cry foul about the dumping of wastewater from Japan.
Japan has sparked controversy in the region by staging the release of treated nuclear wastewater into the Pacific, splitting regional leaders about its safety.
The International Atomic Energy Agency gave the plan the green light, saying the impact on the environment would be "negligible" and Australia has said it supports the science and the nuclear watchdog's assessment.
