G'day Rocky,
Lots of places to check out if you're base camped in one of the Wellington River Camps. Some of the better tracks would be;
Butcher Country
Caladonia River Track (runs almost parallel to Butcher)
Mt Wellington out to Millers Hut and the Sentinels
Mt Margaret Track (from in the National Park and then either north to the B1 Track or south to Hickey's Creek)
Kelly's Lane - nice easy drive but with a few huts to check out.
All bar the Mt Wellington Tracks can be done as a loop. Don't forget Billy Goats, there is a loop you can do but last time we checked the river crossing was out on the alternate track near Rock of Gibralter off the Wonnangatta Road)
If you need track conditions closer to the time give me a yell - we're always up around the Licola/Dargo areas. If you need a 'guide' I might be available too for a day or so!
Tim
PS - some good tracks off the Jamieson Road too!
