Scott Broadbridge has revealed Cassie's trip was a 'surprise'.

What started as a working holiday in South America ended abruptly when Ms Sainsbury was stopped from flying out of Colombia only eight days after her adventure began, when police allegedly found 5.8 kilograms of cocaine concealed in her luggage.

Mr Broadbridge also tells Denham Hitchcock in the interview that he has seen payments from the mystery group.

Viewers will also hear about the drug bust itself, in Ms Sainsbury's own words.

Cassie Sainsbury was arrested and jailed after Colombian authorities allegedly found 5.8 kilograms of cocaine in her luggage.

Ms Sainsbury may be given a 20 year jail term if convicted.

Since her imprisonment she has spoken out about bullying and harassment from her fellow prisoners and has complained of not being provided with adequate food or proper medical treatment.

In an interview with News Corp she said the language barrier was creating serious problems for her and she felt under threat in jail.

Cassandra Sainsbury, 22, is accused of attempting to smuggle 5.8 kilograms of cocaine out of Colombia before a tip-off from the US saw her arrested moments before her flight.

After more than a month behind bars isolated away from all of her family, Ms Sainsbury was visited by her fiancé, and mother and sister – separately earlier this week.

The South Australian couple spent just over an hour together before Mr Broadbridge re-emerged, maintaining his silence as he left the prison.

Just moments later, her mother Lisa Evans and sister Khala Sainsbury arrived carrying two packed bags.

There has been growing tension between the young couple and her family in the handling of her delicate situation.

Sunday Night’s exclusive investigation airs Sunday 8.30 only on Channel 7.
