'Move to higher ground': Queenslanders receive ominous text as dam breaks

Queenslanders living in a town in the state’s southwest have been sent an ominous text message ahead of a dam breaking.

A local spotted a 3.5m hole in the dam on private property at Talgai, north of Warwick on Friday afternoon, but efforts to repair the damage have so far failed.

Residents on nine properties self-evacuated on Friday night after the Southern Downs Regional Council issued an emergency alert.

“Bolzan Quarry Dam expected to fail,” the text read.

“Take action to protect life. Leave now, move to higher ground. Evacuate now.”

The council warned the failure of the Bolzan Quarry Dam would result in "dangerous downstream flooding in low lying areas".

An evacuation centre was opened at Warwick, but has closed as the evacuees have sheltered with family or friends.

The council said water was gushing from a 3.5m by 1.5m hole at the dam's base.

Engineers have been working across the morning to try to minimise the impact of the predicted collapse of the dam, located about 30km north of Warwick.

They have been digging channels in the ground so that if the dam does collapse, the channels could disburse the water and reduce the impact on those living around the area.

The dam holds about 430 megalitres and 14 properties in the immediate area are considered to be in danger, while dozens of other properties could also be at risk of flooding if the dam does collapse.

Meanwhile, showers and thunderstorms are expected to break a severe heatwave that has gripped much of northern Queensland.

Forecasters say the sweltering conditions will peak on Saturday and ease from Sunday, while the rest of the state gets some much needed sunshine.

Temperatures in Townsville, Ayr and Woolshed were well into the 30s on Friday. Days of downpours in the southeast corner of the state have led to flooding that is yet to subside.

The Bureau of Meteorology says there's a medium chance of afternoon showers and thunderstorms for the region over the weekend, but nothing like the deluge earlier in the week.

On the Gold Coast, police are still searching for Yang Chen, 26, who disappeared in the hinterland area while walking near Gorge Falls in the Tallebudgera Valley earlier in the week.
