DH did FIFO for a few years, and it was horrible for us (pre-baby)
We are considering ALL relocating to a mining town next year, if need be, but he wont do FIFO again, while we have young kids.
He did 2/2, which is the best roster but his 2 weeks home were:
Tues night - arrive in Perth after 7 x 12hr day shifts (including that day, with a 4am wake up, and then 8pm arrival in Perth)
weds & thurs sleep
then till the following weekend spend time together
Sunday & Monday Stay up all night to be ready to fly out Tuesday 2pm to start nightshift Tuesday 6pm for 7 days
So we really only had 9 days a month together, or 216 hours, rather than 240 hours or evenings/nights, plus 4 48hr weekends. The money was ok, but we were fortunate enough to find a similar paying job in Perth, and we worked TOGETHER there.

Thats not to say that YOU guys will hate it, of course.
