Barry1956 ,methinks that would depend on where your renting the so called regular house , Karratha WA $2500 per week for long term rental , makes a new house in Muttaburra Qld for $98 per week long term seem positively cheap.
I assumed we were talking about the 'real world', where average families earn 'average' money.
The problem with modern (1970s on) remote mining sites is that they have been allowed to develop primarily on a 'fly in - fly out' basis, so few people actually live there, correspondingly few local votes, little / no long term community relative to the high transient population.
If an owner can get $2500 / week for a house rented to a number of mine workers then I guess they will charge it. However such places are really out of the reach of families on regular money.
Having said that, house rents in cities are already unrealistic.
I know a sole parent in Melbourne who is earning good professional money and is paying $600 / week for a house approx 8km from GPO in the northern suburbs. She earns considerably more than me, but will simply never be able to buy a house.
