When $100,000 landed on their doorstep, Victorians Kevin and Honey were given the option to keep, gift or split the large sum of money.
After decided to keep $75,000 and give fellow struggling family Mem and Troy just $25,000, the parents of two reveal they regret their decision.
'I guess there is a bit of guilt there,' Honey told TV WEEK.
New South Wales parents of four Mem and Troy chose to split their $100,000 evenly between the two couples.
Honey and Kevin - whose construction business went under when several clients didn't pay their bills - admits they felt even worse when watching the first episode of controversial new show The Briefcase.
Quadruple amputee Mandy McCracken and her husband Rod gave their entire $100,000 to farmers Jim and Jenny Carter who also gave away their full $100,000.
'That actually made me feel worse,' Honey says.
'The guilt really got me when I saw that. I said, "Wow, look at both those families, they're amazing" but I also know financially we weren't in a good place.'
The Briefcase airs Mondays at 7.30pm on Channel Nine.
