Jas777: Never going to happen. ABC is funded by Australian Taxpayers so why would they broadcast it to NZ? The only way it would happen is if NZ becomes the 7th state and is treated like Tasmania. Do you want that to happen?
Well, if you go to Europe you will find that there is a lot of cross-border TV watching going on - and not just eavesdropping on satellites. Dutch cable carries British, German, Belgian and Italian channels.
The main obstacle to Australian broadcasters broadcasting to NZ is that NZ broadcast rights are separate from Australian broadcast rights (eg: although ABC own the rights to broadcast Doc Martin in Australia, they don't own the rights to broadcast it in NZ).
I am certainly in favour of a closer relationship with Australia and I think that our separate copyright jurisdiction works to our disadvantage. I would be quite happy if some of the NZ tax that I pay went to the ABC if it meant that we could view ABC TV and listen to ABC radio.
