Totally different on Charter flights put on by the company, in most cases now charter flights won't have any alcohol available on-board for various reasons, and acting like a d@^khead on board will be passed onto company HR so any misbehaviour won't last long. Obviously, some FIFO workers also take normal scheduled public flights, some self-funded and some funded by the company/contractors, some in in high-vis, many others not, due to company policy, again, going hard on the drinks in work uniform will normally end up back at HR and then a resulting one-way "window seat" or even bus off-site forever. The increase in female workforce participation and even senior female managers in the resources industry has also changed attitudes and behaviour over the years, pretty tame compared to what it used to be.
@nancypants - I assume this MacArthur River is some sort of weird hybrid charter/publically available flight linking site to either Darwin or Cairns?
Not everyone in hi-vis is associated with the resources industry, have a look around the warehouse/construction industry/airports/ports/railways/some government agencies/local councils/road & civil contractors etc etc
Another interesting thing is that many FIFO charter flights have gone from free-for-all seating to allocated seating over the years, as aircraft have become larger, and different better seats become obvious, along with the charter operator preferring it. Hot and high performance at some airstrips is still an issue, hence the emphasis on weight saving and minimal baggage/hand luggage as most people have rooms or lockers to keep stuff on-site. Best seats in the house now will be the new E190-E2 when they arrive for Virgin WA or the old F100 or even F70s although there are even better E190 and B737 options with generous legroom and fairly quiet compared to the
worst seats in the house being any seat on a Fairchild Metro on a hot QLD summer day, closely followed by some of the Qantaslink and Skywest A320s with the Tiger interior configuration. Lots of other aircraft such as A320s, A319s, E170s, Dash-8s, ATR42s, E120s, Kingairs and Saab 340s still possible as well, and yes even the dreaded Texas Lawndart (Metro 23) as well in some places.
