Pay dispute, need help!

[Skooter]

Hi guys, My uncle and I are having a massive argument with the boss about money we think we are entitled too.
Basically the story goes like this, my Uncle and I both work for the same company, we were sent to do a job (as it is a very specific industry I wont be describing anything, or naming names) on a mines power station about 1500km from Perth. The job took 12 days and was very hard yakka, in the 45+ degree heat in the sun all day everyday. So the jobs going very badly as the product we were using is incredibly badly designed, so we need more time up there, and my uncle calls the boss to tell him that, he also asks what type of pay we are on up here and the boss says just the normal rate, but you'll be doing lots of hours....Now this seriously ****ed both of us off because we thought there would have to be some kind of away from home allowance or something similar. I could have been earning the same amount of money sweeping the workshop floor in Perth and going home every night. Accommodation and food were all provided by the client at a fly in fly out type village.

So my question is, are we entitled to any kind of extra money legally?
P.s we are both on standard contracts, NOT AWA's and the contracts crack no mention of penalty rates away from home.


Looking forward to your replies,

Michael.
