Whatever (and whoever) deal is found; run it by me first.
After 11 seasons living in Thredbo I know a few peeps in different accom. services and who run/own apartments.
Early September is a good option - but mainly price wise, with several people locked in; even staying on Crackenback Ridge will bring the accommodation costs below $200pp (one of the best ski in/out locations) and beds 14 or more. With large numbers, mid-late Sept the cost could come down to under $100pp.
There is a very special week peak season with no crowds - it's the week following school holidays when no races are on. It will depend on Thredbo event schedules and it's often prior to RIP CURL freeride and FIS races. I've always been amazed at the lack of crowds. It often coincides with Ski Demo Days.
Brandy, (and all other BWM) I'm in Thredbo every other day and travel between SWrnSyd/Wollongong often. I will have my own place in Riverside Cabins your welcome to stay/travel with me.
The conditions of staying with me:
NO obnoxious twits (thats an idiot not an internet blogger)
Accept my obnoxious twittery.
Must cook for me and my flatmate.
If you drink - expect me and flatmate to drink as well - your shout.
If you smoke - same deal as drink.

Your shout!
Most importantly YOU MUST BE UP FOR FIRST LIFTS (or dead) Not hungover or sore from day before dead - dead means no heartbeat/breathing. If you are dead your body will be dumped over the balcony in the river to make room for the next Boardworldian.
You may not pay to stay.
