'Pauline' uses Australian lingo

'Pauline' has been dropping some authentic Australian lingo into the conversation in an attempt to keep up her act.

Despite some housemates already suspecting the new arrival, even sceptic Carole has been taken in by her accent.

While sunbathing in the garden this afternoon, 'Pauline' mentioned that she wanted access to her room to use the "dunny" and collect her "sunnies". And when asked if she liked football, she responded with an authentic-sounding: "Do you mean soccer?"

'Pauline' - really actress Thaila Zucchi - had to do some clever manoeuvring when Liam asked about her qualifications, but she side-stepped the questions by changing the subject or being purposely vague.

Gerry wanted to know if she had seen Kylie at the Olympics, to which she answered that she "wasn't that into" sport.

But when Carole asked about the Australian government, it all seemed to be getting a little too much. After a slightly awkward moment, 'Pauline' murmured: "I'm just not that political either."

While the fake housemate survived the onslaught of questions, it appears the struggle is taking its toll. "She seems really quiet, though, doesn't she?" Sam told Chanelle in the bedroom.
