One week later, the trap is still broken. I had another look at the contact page at NSW Maritime to see who to call. It told me to call 131256 - but when I did so, the options that the computerised voice gave me didn't match what was listed on the website. I had no idea what option is select, so I just took a punt.
At least the bloke that I spoke to seemed to have some idea of what I was talking about. We'll see how long it takes them to hook the boom back up to the trap. I wonder what happened to my first attempt at contact? Have the gremlins been attacking the Maritime computer network as well?
