Liver there for years, left in 2006
Best thing about Karratha is the road out of there
More rocks than dirt. And yes it gets hot n bloody humid. You need aircon running 24/7 for a lot of the year. Outside in summer even at night you sweat dripping wet just sitting down having a beer. Fishing from shore is limited and most of the coast is very rocky which is hard on gear. If you want a decent fish you need a boat. You see lots of big boats there nowadays as you need to go further and further to get a decent catch. There are sports activities and other interests but you need to weigh up the money v lifestyle (or lack of). Also think of your partner and kids. The divorce rate inthe Pilbara is high for a reason, remember HAPPY WIFE = HAPPY LIFE. The one thing you must have if you go to a place like this is have an objective and a plan to get there with a agreed timeline. Without a plan you risk spending your time there working and living in harsh conditions and at the end of it coming away with nothing to show for it. But if you get it all working right then you can kill the pig and get a jump start in life financially.
I'm not saying it's a bad place, just go in with eyes wide open and a clear idea of what you want.
