The report, released on Monday, said China's never-say-die construction sector had showered blessings on Queensland, Western Australia and the Northern Territory.

In the Sunshine State, the big fall in project construction had stopped, Sydney housing prices were sending refugees north of the Tweed, gas output was set to soar and tourist numbers were good despite a rising Australian dollar.

There were reasonable gains in engineering activity in Queensland, and Cross River Rail was in the planning stages.

Housing construction had been supporting the state's growth while mining construction was falling, but now housing construction was also increasingly fading as a source of growth, with the wobbles already starting to hit inner-city apartments.

In terms of the coal pipeline, it continued to be dominated by the multibillion-dollar Adani Carmichael coal mine.

If the Adani mine went ahead, it would give a boost to mining output, Deloitte said.

Mining production growth slowed lately after having been a key economic growth driver for several years after the global financial crisis.

That was not because prices were bad, or because the gains stemming from Australia's mining investment boom had almost rolled to a stop, Deloitte said.

Rather, Cyclone Debbie put a lot of exports out of Queensland's coal country on hold for some time in the first half of 2017.

That meant output growth slowed to below growth in the broader economy.

Queensland was "beaten up" by the end of the mining boom but was starting to see some rays of sunshine from stronger commodity prices, improving population and job news, Deloitte reported.

Job growth was accelerating in Queensland and while population growth had "bottomed a while back", it had now rejoined New South Wales to be in line with the national average - although it remained below the level experienced in the state five years ago.

The growth in retail turnover in Queensland had slowed, and was considerably below the national average, with department stores particularly weak.

But the level of small business confidence continued its rising trend and was matching the national average.

Farm output this financial year had suffered from the effects of a drier-than-average start to winter, especially in northern Western Australia, northern New South Wales and southern Queensland.

Car sales also rose over the past year, similar to the increase nationally.

The Deloitte report predicted the state's economy would grow by 3.4 per cent in 2017-18, up from 3.1 per cent in its June publication.

Treasurer Curtis Pitt seized on the Deloitte report and said it was proof of the government's achievements in job creation.

"Deloitte Access Economics is very optimistic about Queensland's prospects," Mr Pitt said.

"That's confirmed by the fact the very positive DAE report follows the latest ABS figures showing our trend unemployment rate dropping to 5.9 per cent and 122,500 net new jobs being created since the state election."
