Year long trip to OZ/NZ which bag best suitable

hey having real big probs with the bag to get im off in couple of months and need to get a bag quickly...

i was just about to buy the
north face longhaul 30 100litre
http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&rd=1&item=300264887883&ssPageName=STRK:MEWA:IT&ih=020

its a pull along large holdall type thing which looks good and is very lightweight and durable

does anyone think that this is the type of bag i need im going to be traveling around OZ and working etc not so much hiking or anything like that

so i thought this bag is ideal or is a rucksack with pull along handle better..

Rolling bags might seem like a good idea, but personally I did that once and found myself carrying it around more then I was rolling it.

Get a backpack
If you plan on traveling a lot, you're better off packing light and buying stuff you need over there, instead of buying everything you need now and then packing heavy

Edit: Oh yeah... 100 litres is... a lot!
