Vantaggi
Reliable transportation and working conditions at the remote mine sites. I worked in the kitchens, cleaning living areas, and cleaning mine sites for 6 months with a working holiday visa. It was a great way to make some good money as a traveller. They are quick to fly you back home if there's an emergency. While i was working in a remote mine site i found out a family member had died. The had me on a plane back home in less than 8 hours.
Svantaggi
No chance of getting visa sponsorship. Two straight weeks on site with one week home is rough on friendships and relationships. I'll avoid fly-in-fly-out work in the future. There are often a few employees at each location that do as little work as possible. not much you can do about that.
