After Fleur won a ten-star meal in the Bushtucker Trial, it was up to Rita and Harry to win the Dingo Dollars for a bonus treat.
Arriving at their challenge, they read the instructions: "To win the dollars, you’ll need to be bold, and scour the creek in search of the gold.
"When your nuggets have reached the required weight, the dollars will be released from the crate."
Explaining the set-up, Rita said: "We've found this weird looking creek, a sieve thing, scales and a crate."
Harry added: We’ve got to sieve and find enough gold to tip the scales and get us out of here."
The pair got in to their ridiculous costumes and soon emerged ready for gold-hunting.
"I was once in FHM’s sexiest females… now this, where did it all go wrong?" joked Rita.
Harry was also unimpressed. "Looking for gold with Rita in the creek, dressed like this, what’s happened?!" he laughed.
After much sifting through the creek and the sand, they were finally able to release the Dingo Dollars.
Putting on American accents, they sang 'Show me the way to go home' on their way to meet Kiosk Kev at the Outback Shack.
Faced with a choice of crisps or ice pops, they agreed to spent their loot on the frozen lollies.
Kiosk Kev promptly called base camp, where James McVey relayed a teaser question to the other celebs.
"What percentage of the British public would describe themselves as having no religious affiliation - 53% or 33%?" he asked.
Rita and Harry thought it was the higher option, but rest of the group decided on 33%.
It was the wrong answer, and Kev slammed his kiosk window shut, leaving Rita and Harry to walk back empty-handed.
This year's campmates have been struggling with Dingo Dollar Challenges, having won only two out of six so far.
