Venture 1163 tape certainly exists in Australia. It took some running about but I got a roll of it.
I didn't have any luck with anything else though.
Part of it may depend on where you are, and how long you want to wait. I was in Western Australia at the time and tried for local suppliers. No one had it in stock in the Perth offices. In theory they could get it, but unless I wanted to wait a month and get a minimum order - it wasn't going to happen. All were going to order it from the East coast.
Try local, if that fails, call the head office and ask there.
Just noticed, your in Melbourne. Thats where my roll arrived in an overnight bag from.
