What were Australia's most significant mass whale stranding incidents in recent years?

Australia experienced its largest mass stranding incident in 2020 when 470 long-finned pilot whales were found stranded at Macquarie Harbor. This devastating event was followed by another significant stranding at the same location in 2022, involving approximately 230 pilot whales. These back-to-back incidents at the same harbor represent Australia's most substantial mass strandings in recent years, with most of the whales unfortunately perishing in both events despite rescue efforts.
