Storms have lashed Mackay and surrounding areas on Tuesday and Wednesday

On Tuesday record-breaking hail struck with gigantic hailstones measuring 16 centimetres confirmed as the largest ever in Australia's history.

The unexpected large hail fell at Yalboroo, north of Mackay, as a supercell thunderstorm passed over the region on Tuesday approximately around lunchtime.

The BOM confirmed some were the biggest they'd ever seen in the country, breaking the previous record of 14 centimetres set in Kempsey, regional New South Wales, back in 1999.

Meteorologists said they were expecting some storm activity in Queensland the wake of the severe weather on Monday, however the monstrous hailstones produced were not in the forecast.
