Yeah mate its not cheap, I miss the old Combi trader, it wasnt cheap either but the whole experience of cracking a tinny at 5am with the other fisherman and talking about previous trips was worth every cent.
If you have never been I strongly suggest you splash out the cash and go visit the most beautiful place that I have been to so far. A couple of mate's and I go for the tailor every august.
To be honest if I had the deciding vote whether to keep the barge fee's as they are or quarter their price I would keep them as they are, I love the fact that there are hardly any people over there (no doubt due to the cost). We camp on the eastern beaches and feel like we have the whole island to ourselves.
I am going to try and do a weekend trip over there before the end of august this year to take the missus and kids over. I agree that it is a pretty expensive weekend but over a week the cost evens out not too bad, especially if you split it up between a couple of people in the car.
