Recently, Kyle and Jackie O held a competition where their ‘Cashed-Up Sisters’ hid around in Sydney in secret locations.

The guys then revealed the clues and the race was on to be the first person to ask the question, ‘are you Kyle and Jackie O’s Cashed-Up Sisters?’

After two unsuccessful locations, it was time to move on to the third, which had jackpotted to an insane $50,000.

The first person on scene once the countdown started? Serge, a 27-year-old plumber who was working in the area.

Needless to say when he asked the question, his whole life changed.

Congratulations Serge!

All thanks to the new show, Sisters, 8:30 Wednesdays on Ten.
