The problem with LRE is actually airline yield management. BNE-LRE can be had for as low as $65-$75-$79 one way on sale, ~6 months in advance... The problem is getting 50 seats at that price.
There has been some discussion about chatting to QF directly about establishing a group rate which would be "fair" to both parties, and let us take a larger group. Most of the attractions in LRE can handle a group of that size, especially if we split into different groups for some of the key activities such as the "Wing Walk" at the the QOFM (Qantas Outback Founders Museum). Large groups actually work in our favour for activities such as a cruise on the Thompson River, and the Australian Stockman's Hall of Fame & Outback Heritage Centre, as they offer group discounts.
Accommodation should be fine, as long as we don't pick a weekend with another major event.
I think we could do LRE as an event at some stage, but someone (not me) would need to take ownership of organising the logistics, and liaising with QF, etc.
