Queensland Premier Campbell Newman has blamed the Federal Government for adding to the state's worsening unemployment situation.

Deloitte Access Economics has released its annual snapshot of the Queensland economy.

It predicts unemployment will rise because investment in new mining projects has waned.

In June, Queensland recorded a jobless rate of 6.4 per cent - its highest rate in almost a decade and noticeably higher than the national average of 5.7 per cent.

Mr Newman says the Rudd Government is stalling on approvals for new coal mines in the Galilee Basin and it is costing the economy dearly.

"Immediately we'd see over 10,000 jobs being created during construction and we'd see billions of dollars of investment coming to our state at a critical time," he said.

Deloitte says despite predicting a rocky ride for the next few years, Queensland's long-term economic outlook is good.
