Adamastor,
Am not even sure those numbers are correct - just what we were told by an ops director here (he is one of the better ones so more likely to trust him!) but it is most definitely the cr@ppy scehduling of the FIFO contracts that makes life a misery. I totally understand this is NOT Skippers, Networks, QFs, etc. fault - it is BHP, Rio, Woodside, etc. demanding that all their crew change-over at the same time.
It would not surprise me to find out that our average is 300 moves/day with peaks over double that - Mon arvos, Fri mornings and weekends are generally quiet, far removed from the craziness of Tues, Wed and Thurs morning and arvos.
Maybe the FIFO contract holders need to talk to the mines about spreading out the moves to cover the whole week, not just predominantly within three days?
