I don't hate it but out of all the places I've been (I've backpacked Europe, Aus, SE Asia and South America and visited various other places for extended periods of time) Aus was the least enjoyable trip.
It's full of Aussies for a start. Need I say more?
At the time I enjoyed it but having been other places it pales.
Great nature and scenery and some things I'm really glad I've seen and done.
Go for it and enjoy it. I'm sure you will.
