The Block 2025 is nearing the end, and contestants — and fans — are gearing up for the all-important auction day.
On The Block, each house is set a reserve price at the end of the renovations. In the past, the reserve has varied depending on the size of the houses. However, every house this year has identical layouts, so they should all sit around the same mark.
On auction day, contestants get to take home whatever the houses sell for over the reserve. The house that has the highest amount of over-reserved money scores an extra $100,000 in prize money and is crowned the winner of The Block. Last year’s winners, Maddy and Charlotte, pocketed a whopping $1.65 million, including their winner’s prize.
While the winner of The Block 2025 isn’t officially revealed until the live auction, fans are sharing their predictions online, and there seems to be one team that viewers are convinced will win.
On top of that, in September, Australian betting site Sportsbet indicated which team may be walking out of the auctions triumphant. The odds have since been taken down now that the auction is nearing.

Who do viewers think will win The Block?
The Block Facebook group is overflowing with fan predictions about who will win this season — and the overwhelming favourite is House 3, renovated by Britt and Taz.
However, House One (by Emma and Ben) and House Five (by Mat and Robby) are also popular choices among viewers.
One user even questioned if any of the houses would sell without Adrian Portelli and Danny Wallis spending up big at the auctions.
“It’ll be interesting to see if anyone wins. Their reserves are quite high and for any of them to walk away with substantial money the houses would have to sell for about $3.5 million. It’s a lot of money. Not sure they’re worth that much or there’s too many people around prepared to pay that,” they wrote.
What are the betting odds of who wins The Block 2025?
In September, fan favourites Robby and Mat had the best odds to win The Block 2025 with a return of $2.00, and Emma and Ben were second with $3.25.
Britt and Taz sat in the middle of the pack with a return of $4.00, and Sonny and Alicia were fourth with $7.50.
The betting website had Han and Can with the worst odds to win the show, at $10.00.

How do betting odds work?
Betting odds are tied to dollar amounts, and those with lower odds are recognised as more likely to win, hence the lower return. For example, if someone bets $1.00 on Mat and Robby winning The Block and they do, they’d receive the amount that outcome is listed at, which is $2.00.
The return is based on how much someone bets, so if they bet $10.00 on the same thing, they’d receive $20.00. If they bet $100, they’d receive $200.00 and so on.
The Block 2025 airs on Sundays at 7:30pm and Monday – Wednesday at 7pm on Channel 9 and 9Now.
