Sorry, I haven't been around here much lately - will be back for BBUK4!
I've found that the BBOz website has been better than the UK one (it's only just been relaunched so doesn't have much info on it at the moment). Last year it had loads of news (normal & of a more 'adult' nature

- not for kids eyes), a running log - very good and updated quickly most of the time, diaries written by the housemates while they were in there (on a laptop which they also did their shopping list on too). They only had free cameras for BBOz1 although I think the movable camera was free and you could see clips (or was that the first year?!). Hopefully will be as good if not better this year although they seem to be following the trend of having to pay for 'premium' content, which I think spoils the interactivity of it (especially when you're on the other side of the world!

).
The series looks promising. They have entirely gutted the house to start from scratch so there is lots of surprises - unfortunately it looks like they may have the dreaded bars too

.
This seems quite a good unofficial site:

P.S.
News on Marty & Jess (BBOz2's version of our own Paul & Helen!):
Both now live on the Gold Coast with Jess' mother. Late last year Jess lost her brother in the Bali attacks. Marty signed up with Nickelodean to present its new adventure show 'Nickelodean Islandares'. Jess turned up on The Panel a few times, worked for Nova and the two also co-host the Sea FM breaky show on the Gold Coast.
