Don't mean to hijack the thread (no pun intended) but it looks like locally QANTAS (the flying bastards) are looking to change all domestic luggage rates from the 1st of December this year.
Economy will be 23kg MAXIMUM
Every kilo over is $10
We do a lot of flying for work with a lot of gear.
recently just got pinged for an extra 5kg of luggage between a crew of four... 2 of whom were gold frequent flyers... they even wanted to weigh our carry on

Got a couple of interstate trips lined up with gear (both work and sailing kit)
Will report back in the coming weeks but from what I have seen, read and heard the days of shipping sailing kit across the country with little to no excess charges will be a thing of the past come December 1.
Qantas have also started promoting the ability to buy additional excess luggage kilos at cheaper rates PRIOR to check in
