But the pair's potential win with their $20,000 auction earnings was eclipsed by Nate and Andy when the Hamilton pair were allowed to return for a second go at the auction.
They scored $31,000 over reserve, scouping the show's $100,000 prize and leaving Stace and Yanita visibly shocked.
Many claimed their second chance at the auction was unfair, but Three said: "This is a reality of auctions and keeps the bidding transparent."
Stace and Yanita are yet to discuss Sunday night's loss, but Cottrill's bad luck continued last night when she saw her flight home cancelled.
So she took to Twitter to compare her missed flight to Sunday night's controversial auction.
"Flight home to Palmy cancelled," she wrote on the social networking site.
"No wait. Maybe they awarded me the seat. And then decided to take it away?"
One viewer replied: "im glad u can laugh about it stace! so unfair! u both did an amazing job! have a safe flight home." (sic)
After the second auction controversy, Nate and Andy called their win "bittersweet".
However, they said their $130,000 winnings weren't enough to share around with their fellow contestants, who spend three months renovating homes potentially for no financial reward.
A Givealittle page set up for Stace and Yanita has so far raised close to $2000.
Another, for contestants Zing and Ling, who took home just $1000, the equivalent of working for 12 weeks for $0.48 cents an hour, has raised more than $16,000.
