Queensland’s economy is in the middle of a slump worsened by natural disasters according to the latest Deloitte Access Economics report on Australia’s finances.

The state government already announced $1.3 billion for damage caused by droughts and floods, but the independent Deloitte report estimates the figure will be closer to $6 billion.

Queensland Deputy Premier and Treasurer Jackie Trad said Deloitte is basing that figure on multiple metrics over different timeframes with a broader perspective than the Queensland government’s assessment.
