So landed back in Melbourne around midnight last night after a weekend away. Returned to my bike which had been parked in the motorbike section only to find some a$$hole had stolen my helmet. I'd locked it to the under-seat helmet hook, looks like they yanked or ripped the strap off to take the helmet. Completely useless to them as the D-hooks were still locked to the bike. Called the police who took details but couldn't do much about it, obviously I couldn't ride home with no helmet either so had a long journey home. Just wondering if anyone familiar with the airport knows if there are any security cameras around that area (I couldn't see any), and also if the carpark/airport is liable for theft like this (considering the expensive parking fees they charge)?
