The construction phase is always a problem -- road trains. heavy haulage. (randy) workers looking for a distraction and any number of other issues.
Where there is one development the mindset becomes "well why don't we put a .... plant next to it to value add" as Mr Kumah from Peppi Grove would like to do in the Pilbara with his proposal. And at the LEAST there will be virtually a small town built to support the facility and its construction because I can't see a whole workforce traveling to Broome and back daily even if Broome could house them.
One of my first jobs (33 years ago) after high school was in Wickham in the Pilbara and Karratha, as most WA lads and ladettes would know is just down the road. Karratha and Dampier had iron ore facilities and some salt lakes but was still an interesting and fairly easy going place to live. It has taken considerably less than those 30 odd years to become a s..thole mainly suitable for making swags of money (of which most goes on living expenses) and has not much else going for it.
My main issue with building a "gas hub" on the Dampier Peninsula is that in very little time we could end up with a mini Burrup/Karratha on what is essentially a near to pristine stretch of coast that is relatively easy to access if you wanted.
I'll let you know after May when I get back from there if I will join the ferals to protest or just roll over for the good of the nation.
It's a little like Oakajee hey ??

but without the sailing......
