Former foreign minister Julie Bishop is guest this week on the season final of Andrew Denton: Interview.

This week on Andrew Denton:Interview meets with Jessica Mauboy.

This week, one of the toughest challenges of Andrew's career: how do you interview a friend of 40 years, someone you've known since you were teenagers, someone you've worked with, laughed with and already shared most of your life with?

Andrew and Amanda met at Mitchell College in Bathurst (now Charles Sturt University) when he was 18 and she was 17, both fresh out of high school. They've worked together on TV and radio, and generally been each other's biggest supporters.

"I immediately knew we were going to be friends," Andrew says of their college introduction, "and we have spent the last 40 years trying to either shock each other or make each other laugh. Often, they've been the same thing."

So how do you make an interview like this work? You reach into your loooooong memory list of funny and embarrassing moments and celebrate Amanda, one of Australia's favourite women, by letting her remind us all what a smart, funny and occasionally super daggy human she is.

It's the most fun you can have with two people and two chairs.

What would you do if you discovered the person you'd been having a six-year romance with didn't actually exist?

This is exactly what happened to entertainer Casey Donovan, winner of Australian Idol and I'm A Celebrity, Get Me Out Of Here. The singer was catfished, manipulated into an imaginary affair by a woman pretending to be the man of her dreams. Having been lured into the relationship, her abuser then used Casey's vulnerabilities to keep her locked in.

"In the beginning I was like, this guy has to be real," Casey tells Andrew. "And then as the months turned into years, I stupidly didn't tell anyone that I'd never met this guy ... I was just creating this big ball of lies."

In a frank and fearless conversation, Casey takes us inside the waking nightmare that she lived for those six years and details how she's put her life back together since.

"The more I found out about it, the more Casey's story just blew my mind," Andrew says. "It's one of the most remarkable tales I've come across in my career."
