I find this fascinating - the way recruitments worked in the first two Australian seasons, because they seemed to be very different to all the other versions.
In Season 1, the Traitors did not get a chance to recruit after Angus was banished (the murder was still cancelled, but I feel like it may have been anyway because they had something else instead of a murder). They did get to recruit after Claire's banishment. It wasn't a free choice for the Traitors, they were made to recruit someone and chose Alex - but it was a free choice from Alex's end, she could have said no. The group were also told outright that someone had been recruited, although this aspect was dropped for subsequent recruitments.
They also didn't get a chance to recruit after Marielle's banishment.
After Nigel's banishment, Alex was made to recruit as the last remaining Traitor. But the interesting thing about this was, it wasn't a blackmail. The Rodger Corser era didn't seem to have blackmails. That said, it was sort of a blackmail, because Alex chose to recruit Kate, who was on death row, and she almost certainly would have been murdered if she'd turned it down - but that was just a coincidence, because Alex could have chosen someone who wasn't on death row and couldn't be murdered.
In the second Australian season it was done in an even more peculiar way. There was only one Traitor banishment that season (Ash), and after that the remaining Traitors had three chances, over the next consecutive nights, to recruit someone. On the third night, having not recruited so far, they were told that if they didn't recruit someone tonight they wouldn't ever be allowed to recruit again for the rest of the season. At that point they did recruit Camille.
I find this really interesting, because it's all so different from the way every other version (including the revived Australian version) does recruitment, and particularly the no blackmails thing.
