The giant hailstones measured more than 16cm (6in) in diameter, Australia’s Bureau of Meteorology said today.

They hit Yalboroo when a storm swept through the small town about 1,000km (621 miles) north of Brisbane yesterday.

Social media images showed the icy monsters spilling out of people’s hands, and huge hailstones were seen smashing down in front of a car in one video posted on Twitter.

“Yesterday’s 16cm hail in Yalboroo, Queensland is a new Australian record,” the Bureau of Meteorology tweeted.

“The atmosphere was extremely unstable, which allowed hail to continue growing before gravity forced it to the ground.”

The previous record of 14cm was set in southeast Queensland state in October 2020, the bureau added.

There were fresh warnings of severe thunderstorms along Australia’s east coast today, with reports of giant hailstones striking for a second day – this time in the coastal town of Coffs Harbour, north of Sydney.
