Thanks for the reply. Checked out their website. Looks like you need to be a pilot or club member to use their camping facilities.

Mate, how long are you looking to stay and what time of year ?
There are several different options depending on the above
Also.. Are you looking for lots of on site goodies ( not showers and the like as they are standard.. but club house, restaurant, wifi and the like )
