To all you 'jetski dislikers'....
I live in Tassie, I use my jetski responsible, we ride to remote location, I see nobody most of the time, Tassie has some very remote spots only accesable by boats, in the greater Hobart area there is only 200,000 people.
I am guessing you guys may be a tad annoyed we have this awesome state to ourselves.
Please don't knock something until you have tried it
