Sophie Cachia and KJ Austin no longer speaking after Australian Survivor

When the cameras were on, influencer Sophie Cachia was close to her sister and Survivor team mate. Now the show’s over, they don’t have a ‘whole lot to do with each other’.

Survivor runner up KJ Austin and sister, influencer Sophia Cachia are no longer on speaking terms following their stint on the Ten reality adventure series.

Their estrangement made for an interesting vibe with both attending Channel 10’s exclusive corporate marquee at Melbourne’s F1 on Friday, Austin with her Survivor contestant cohort including winner Mark Wales, his wife and Cachia’s nemesis Sam Gash, and her other frenemy Khan Ong.

Cachia attended the marquee as a guest of motorsport expert Mark Skaife’s wife Tomi.

A sibling stand off had VIP guests rubber necking from the F1 cars to the marquee media wall.

Daughters of former Fitzroy and Adelaide coach Robert Shaw, Austin told Page 13 the two fell out after leaving the show.

“At the moment we haven’t had a whole lot to do with each other, maybe it’s a sister thing,” Austin said.

“She did support me for awhile … until she didn’t.

“The reality crossed over into the game for her, but for us, look at us here, we are all great friends.

“I didn’t win. So it was really important I came out of the game with some positive memories.”

“I just want to enjoy myself.”

Austin said she cherished her time on the show but in a true blue Melburnian story spent part of the game more worried about her husband’s antics … in trade week.
