Counterfeiting challenge begins

A licence to print money was handed to Sara, Kathreya and Rachel as part of their section of the shopping task.

However, the trio had to produce $100,000BB in less than one hour in the middle of the night.

Sara was in bed when Big Brother signalled the start of the criminal activity in the early hours.

Inside the task room, the robbers were faced with piles of paper, stamps and washing lines on which to dry their fake notes.

The counterfeiters started off in good spirits, singing and congratulating themselves on the production line they had rolled into operation.

As the task wore on, the small talk stopped and the housemates focused on trying to complete the job.
