Good laugh. Summer can be worse, swear standing in a sauna when outside.
Ems,
Wide range of site conditions depending on location. Some places I didn't mind, others glad to get the hell out of. Construction ie 2x3m donga vs permanent accommodation. Office work is at least air conditioned. I've worked with a few imports, ie Irish etc and its not the first time one has keeled over in a faint outside.
From my understanding most of the FIFO 8/6 schedules have all accommodation costs, maintenance etc taken care of for them.
As a guy I would say being a woman is less of an issue these days. Yes you will be a point of interest especially if on a high% male site, we get sick of looking at each others ugly mugs. However these days most realise a single out of order comment or action will get them on next plane out.
I've only really ever seen one person overstep bounds he was thrown out the wet mess and offsite next morning.
Personally if the pay is appropriate go for it. Spend a few years doing it and make some savings. You will have 4-6 days straight with significant other.
Young children then perhaps not.
If site happens to be seaport related, I have been to most in WA.
