WA's peak mining lobby says government must work with industry to boost the state's productivity if it is to fill the next pipeline of resource projects.
The Chamber of Minerals and Energy has released its state growth outlook report for 2013, saying the industry is making the transition from construction to production.
The chamber's Reg Howard-Smith says the next five to 10 years is positive, with up to $200 billion worth of new and expanding projects.
But, he says the next pipeline is yet to be secured.
"We do wave a little bit of a warning flag," he said.
"We are not seeing, at this stage, any other major construction projects being proposed.
"I know a number are under consideration, we only hope that those considerations lead to further announcements." Mr Howard-Smith says high labour and production costs are putting future projects at risk.
"We don't see any major projects beyond the next few years," he said.
"I think there's a clear indication to politicians, to policy makers that what we need, certainly a more conducive economic environment but there's a lot of work to be done in actually making it more attractive to invest." The Planning Minister John Day says the report helps the Government plan for future growth.
"It is certainly helpful having this sort of information provided by the CME with the extensive survey of all their members," he said.
"They are, of course, closest to knowing what is likely to happen in the medium term and we do appreciate having this information available."
