I may be wrong but I thought they said something like, 'You will be an Ambasador for BB, the 1st part of the challenge will be to deliver a message to BBSA.'
Which led me to conclude that there was a second part of the challenge, possibly another message delivered to somewhere else. I thought it was most probably Australia & that's why he escaped nomination for 2 weeks. Gaetano only had immunity for a week.
The press reported that BB were still in negotiations with BB Australia, while Cameron was in SA so he was flown home when the week finished.
It made sense at the time because he was already halfway there & wouldn't have suffered jet lag. In the end of course they sent Annuska.
Does anyone else think that the original intention was for Cameron to go on from BBSA to BB Australia?

In BBSA they only had nominations once a fortnight therefore gaetano didn't miss out so to speak.

No, it was because they only had to live with him for 3 nights. First night he went to bed early because he was tired. Second night he almost lost his virginity. Third night he shouted at someone and danced around.

It might have seemed like a week - but Cameron did actually only spend 3 nights in the place. It makes it all the more ridiculous that he had two weeks' immunity..
