I'm in Australia also and have (amoungst other things) worked FiFo on and off for four decades now .. mining & resource companies certainly pay for the flights to and from the work place .. and provide accomadation while there.

I live outside of Perth, if I consult | work for folk in the big smoke I quote charge for time on deck + travel allowance .. if I'm travelling for their benefit it's detracting from time I could otherwise spend on myself or other clients.
