Queensland authorities said major flooding was underway in coastal Hinchinbrook Shire, a locality of around 11,000 people located about 500km (310 miles) north of the state capital Brisbane. Authorities said several suburbs in the nearby city of Townsville were also impacted.

North Queensland has large zinc reserves as well as major deposits of silver, lead, copper, and iron ore, with Townsville a major processing center for the region’s base metals. In 2019, severe floods in the area disrupted lead and zinc concentrate rail shipments and damaged thousands of properties.

“Residents in low-lying areas should collect their evacuation kit and move to a safe place on higher ground. This situation may threaten life and property,” regional emergency management authorities said on Sunday morning.

The flooding was triggered by heavy rain from a low-pressure system rich in tropical moisture, Australia’s weather forecaster said on its website, adding that 24-hour rainfall totals were likely up to 300mm (11.8 inches).

“The potential for heavy, locally intense rainfall and damaging winds may continue into early next week subject to the strength and position of the trough and low,” it said.

Frequent flooding has hit Australia’s east in recent years including “once in a century” floods that inundated the neighboring Northern Territory in January 2023 during a multi-year La Nina weather event.
