Australia bushfires: Thunderstorm brings woes of a different kind to Australia

As Australia battles to contain record-breaking bushfires, a severe storm has brought another problem to the country - flooding.

Heavy downpours hit southeast Queensland on Saturday morning (local time), with 325mm of rain falling in the Gold Coast and more than 200mm in the Gold Coast hinterland, according to 7 News.

The deluge flooded multiple roads in the state, with police receiving 50 reports of flooded roads across the Gold Coast.

Bureau of Meteorology (BoM) forecaster Kimba Wong called the rain a "one-in-100-year-event".

"The highest total that we have recorded is 330 millimetres at Loder Creek on the Gold Coast, so some very heavy rainfall there," Wong told ABC.

"We did have an emergency warning in place for that rainfall because we had some reports of flash flooding in some locations and in some locations it was a one-in-100-year event."

The BoM said showers and thunderstorms were still possible over the weekend, but heavy, intense rainfall had eased.

"Take care on the roads - if it's flooded, forget it," the BoM wrote on its Twitter account.

The Queensland Fire and Emergency Services (QFES) also warned residents to stay away from flooded streets.

"Fast-moving water can be extremely unpredictable and have devastating consequences.

"While we have highly-skilled and well-trained swiftwater rescue technicians on standby right across Queensland, please don’t put their lives or yours at risk."

Theme parks Warner Bros Movie World, Dreamworld and Whitewater World Theme Park were all closed on Saturday due to the rain. 

Despite the danger, the heavy rain did bring some relief to fire-ravaged zones.

In neighbouring New South Wales, rain had fallen "across most firegrounds" on Friday, the NSW Rural Fire Service said.

As of Saturday evening, 69 bushfires were still burning in the state, 19 of those out-of-control.

"Rain continues to fall across a number of firegrounds, however the Far South Coast and along the border are still yet to receive any moisture," the fire service said.
