it's AusNTM, they look for a good rolemodel. in case you didn't my point earlier (happens if you stan for someone i don't like), it's a family show. with the way Cassi acted, it would have sent the message "behave like a brat and bully people, it'll get you on top" and they had that already with Demelza and didn't want another one like that.
and no, i'm not biased towards Clare. my original favorite was Laura M. but Clare grew with the competition and personally, i find her attitude engaging and funny. so, she's a bit stiff, but it's her own choice. while some of you don't like her for her personality, you defend Cassi's personality with her photos.
