Jay: I've been acting since I was six when I did a Spaghetti Oops commercial. I haven't eaten canned spaghetti since. It might be because we did 400 takes!
Jay: (asked what he does when not filming "Sea Patrol") I spend a lot of time at auctions. I go through old gems that nobody wants, polishing them up and finding them a new home - anything from 1960s furniture to antique frames and general bric-a-brac.
Jay: (on working on "Sea Patrol") It's like being six years old and getting paid to muck around with your mates! My favourite cast member would have to be the good ship, HMAS Hammersley.
Jay: I always seem to get parts where I play the sports professional - and that's not me at all!
