It's improved though. I used to date a WRAN in 1977 in Darwin. I'd literally drive into the base loaded up with my Ruger 44, Ruger 10/22 and a Boito .410 shotgun lolling about in the back of my Landcruiser troopy ready to head out to the 50mile to blow up termite hills.Seems to me that the main problem at Coonawarra is the base access both by road and by sea. Decent control at the gates and close monitoring of the basin by CCTV from the tower would probably solve the problem. Its a base problem not a boat problem (provided current procedures are adhered to - you hint that they were not)
Never got checked in or out. Apparently if you're dating a WRAN then you were trustworthy
