I wish !
No you can't
But if you subscribe to "Foxtel DIGITAL " you do get Sky News UK 24 hours a day as a separate channel. I'm afraid you wont get the 100's of channels you are used to in the UK. You also get BBC world but NOT BBC News 24.
If you have a UK credit card and a little bit of tweaking you can subscribe to realvideo and watch some UK stuff via broadband ( e.g Channel 4 documentaries ) but its not real time.
A new device will come out for Europe early next year called the Slingbox ( its in the USA already) that will do real time TV.

Basically you give it to a friend (it will have to be an understanding friend) in the UK who has a broadband connection and you loop the video output from their VCR or cable box through the Slingbox and their broadband connection . You can then access the Slingbox from any broadband connection in any country, change channels back in the UK or play a VCR recording, the slingbox streams this across the internet to your PC. Should be out sometime next year in Europe for UK TV format. I'll be buying one !
