The Gold Coast couple made their debut on The Block Glasshouse and left the show with only a $10,000 in profit. But only a year later, they went back for round two as they competed on Reno Rumble.
Now though, it's a third time lucky for the family as the Duffys' children Paddy and Stella, will also feature on Ready Set Reno.
Australians will see the happy couple renovate their home and travel across the nation on the quest for some makeover inspiration.
We have no doubt their tots will be excellent travel companions as they've spent the past few months travelling with their parents in Singapore and the US.
Check out a sneak peek at the new show below!
