It's not too hard to get dry ice (or liquid nitrogen) and a styrofoam box to do the low temperature; I'd think that dust ingress testing in Australia would be pretty straightforward ;). One thing not mentioned, and a bit harder to simulate, is that the altitude is rather high at some stations which can make cooling problematic.
