The Block's Steph and Gian reveal strategy that helped them win

"There was a lot of thought that went into that."

The Block's Steph and Gian were left shocked on Sunday night when they sold their renovated house for $5 million, earning themselves a huge $1.65m in profit and $100,000 in prize money, breaking the record for most money earned on the show.

The pair, both 27, have now revealed their step-by-step strategy to win in an interview with Daily Mail.

"When we got the call that we were on The Block in February, the first thing we did, I think three days later, we called Tom Spanos our auctioneer," they said. "He was the first person we called and engaged, and people probably wouldn't think that. As soon as you find out you're on The Block, why would you call an auctioneer?"

They added, "For us, it was the end game. There was a lot of thought that went into that. The team at Ray White Sunbury are exceptional."

The couple also shared that it was a "no brainer" to use the same agency that helped Omar and Oz win last year.

While other teams went home after they finished filming, Steph and Gian stayed in Melbourne for the three months until Saturday's auction, using it as a chance to network and meet buyers face-to-face.

Adrian Portelli shocked audiences when he bid $5m for the property, with the investor later buying Eliza and Liberty and Kyle and Leslie's properties, spending a total of $12.4m.

Steph and Gian were initially worried they wouldn't make much money, given their reserve price was so high at $3.35m.

Bidding on the property reached $4m, but when a woman fainted, the bidding was stalled. However, Adrian quickly got the bidding up to $5m, leaving the couple shocked.

During an appearance on the Today Show on Monday morning, the pair said they will be selling their home in Sydney and will be using the prize money to continue their renovation journey, as well as launching a homewares business called Japandi Estate.

Speaking with 9Entertainment, Gian said of their huge win, "It's life changing money, we wouldn't have expected it. We're just glad that Adrian Portelli saw the value in the house that we saw as well. We are so grateful, he's changed our lives."
