I dont think the 12K Broome allowance or the 1K Darwin allowance will go very far at all.
They are both very expensive cities.
People in Karratha are paying $4-500/wk to rent a ROOM in a house.
A 3x1 house was reportedly renting for $80K/yr on news earlier this week.
I assume Broome will be very similar???
If so your 68K base bay isnt going to go too far at all.
Just before the GFC hit they were paying over 70-75K or more I think it was for a Broome FO with FIFO available.
