There are quite a few Australian R4 DVD's which are R2 (UK) compatible. I purchase quite a few of my films from Australian sites (

because they are usually cheaper and are released sooner. A good example of this is the new Back to the Future Trilogy which has just been released on R4. First off it isn't released on R2 until December, secondly it's going to cost about �28 on R2. I got mine from CD-Wow.net (

for only �17.99. You may find only a few Australian sites list whether the discs are R2 compatible or not but you can check the majority by going to

This guy has tons of reviews of R4 discs and he lists the Region compatibility. Hope this helps.
