Read the optimal employment article and I'm wondering if this is still current. The mining boom over here has resulted in a lot of low hanging fruit in terms of labouring jobs that often have six figure salary and provided living conditions if you're willing to live in some of the more remote areas. I honestly have no idea what the conditions are around visas and background or what the competition is like, but it's this formula + more stable work and higher income for a comparable skill range.

Lots of fact checking required on what I'm saying here but I know there's other import labour around a lot of the mining areas right now, it may be a good vector?

Edit for additional data points: I'm currently working in the Queensland mining industry. The role adds about +25K income for my skill set (although for basic labour and retail the gains are closer to +50K) and the living costs are between 10-20K lower than in the major cities. The work / life balance in terms of hours is slightly worse, but the commute is 10 mins from my door to work. Culture and "liveability" of the city is quite low compared to metros. As a result of this latter point though I've had the time and disposable income to pursue several hobbies, and further education, without too much of a strain.
