Bubbles Laundry

Easily found on the same side of the road as Coles. There's Pizza next door and great noodles around the corner.

8 washing machines, from $6 per load depending on wash type.
11 drying machines, $1 per 5 minute.
There is a change machine.
There is a soap machine (though it is right next to Coles).
There is free wifi - password taped to the wall.
This is manned sometimes and there is an ironing service - though grotty yachties have little use of this.
They will also pick up and deliver - very useful if you don't fancy the trip.

This is about a 1.2km / 15 minute walk from the jetty. It is possible, I'm told, to tie a dinghy up in the stream running alongside Coles. I haven't tried this and you'll probably need to be creative as the bank is made up largely of boulders. If you're game, its only a couple of minutes to the laundry.
