Coming from UK - need good advice!

Hi everyone, my name is David and I am coming to Tassie from Scotland on 24th June 2011 for three weeks...yeh, yeh I know its winter but that's when my son can get some time off work! Anyhow, I am very OK with Scottish winter conditions and have read all about how its unpredictable there, just like here, can change anytime from sunshine to blizzards and wind chill like your ?!@$ fall off. Also been in Rockies, Atlas and Caucasus so like a bit of adventure.
We'll be in the St Clair area for 3/4 days and I've read a good bit and got the 1:100,000 map for the location and we'll have our winter 5 layers etc. but never bush walked/trekked in Tassie before, I wanted some advice:- what's the best route up Mount Olympus? any tracks/paths once off the overland trail or cuvire valley track on the route? can I expect to do it in a day round? what snow and ice to expect - will we need crampons? how hard is the bush walking off track? Also could I do Rufus and Hugel ridge in a day round at that time of year or is that stretching it? any other good advice apart from don't be stupid!
Maybe bump into you....................see you soon.....David
