An independent review into the floods that hit Brisbane earlier this year has found residents could have been given more warning.

The review by former governor of Queensland Paul De Jersey has found that it was a “worst case scenario for Brisbane and its people” and a true calamity, that has left people displaced as well as some businesses closed.

23,400 properties and 177 suburbs were impacted, almost double the amount impacted of the 2011 floods.

37 recommendations have been made to the Brisbane City Council.

It found the SMS emergency alert system was “inadequate, slow” and reached only 14 per cent of residents.

It also recommended more than two evacuation centres in Brisbane, and voluntary home purchases schemes should be re-instated.

Lord Mayor Adrian Schinner says the council will accept all recommendations.

He said residents can opt to sign up to the council’s Early Warning Alert service, but there were huge delays of “hours and hours” for the national alert system.

“That was the one where we had really major problems,” he explained on 4BC Drive.

“This system needs to be fixed, it needs to be sped up, and that’s something we will talking to the state government to get that working, and it needs to be going before the next storm season.”

But Cr Schrinner admitted more residents need to sign up to the council’s alert system, and it needs to be incentivised.
