Was just looking at flights to Melbourne and Christchurch. Last year I booked 20kg and took ski's,board and clothes. Bag number didn't matter,only weight.
Just went to rebook the same flight. Now need to book a minimum 15kg checked baggage at $17, plus a flat $25 for a snowboard per leg (and its weight is still part of your checked baggage). At least Tiger lets you book the board for the same $25, but it includes 20kg. So don't need to book checked bags on top.
So a simple cheap ski trip to Melbourne is now a minimum $25x2=$50 + $17x2=$34. So $84 before the fare is even considered.
If travelling on to Nz etc, double that.
I'm sure a few Nz / Bali travellers might be in for a surprise.
More reason not to fly Jetstar.
