The Queensland government has started looking at design based business initiatives to try and offset the slowdown in the mining industry, I'd consider this a reasonable leading indicator of what you're suggesting here. Has gained very little traction though.

There's also a partition between raw project labour, and subgroups in the overall resource economy. Project based construction roles pay well with fixed terms, mining and refining sectors will slow down, gas sector is starting up at the moment (project based) but won't yield many jobs once it goes operational (can run the buggers with a handful of people).

Still has a healthy decade left in it, give or take, so isn't a bad option for short term transient jobs.
