The Block and Married At First Sight could be set for a crossover in a rumoured celebrity season of Nine’s hit renovation show, but fans are outraged over the move.

The Block is set to get a lot more glamorous, with the Nine Network reportedly eyeing the Married At First Sight cast to participate in an upcoming celebrity edition of the hit renovation series.

Nine has floated the idea of a forthcoming season featuring some of TV’s famous faces as new Blockheads, including MAFS’ Martha Kalifatidis and Michael Brunelli, according to the Daily Mail on Monday.

The publication reported other MAFS alums Dave Hand and Al Perkins, comedy duo Hamish Blake and Andy Lee, and Olympic legend Cathy Freeman are some more familiar faces at the top of Nine’s long wishlist.

The idea of the reality TV crossover comes as production insiders say executives at Cavalier Productions, which produces The Block, are in search of Australia’s most loved TV talent to pack a punch into the show.

“They’re seeking instantly recognisable personalities who will bring charisma and energy to the build,” a production insider told Daily Mail.

“It’s not just about picking up a hammer – it’s about giving viewers the kind of moments they’ll still be talking about the next day.”

Another source said this goes beyond merely chasing influencers for their follower count, and the chosen cast will have well earned their reputation.

“They want Australians who’ve earned their place in the spotlight, who are respected, and who’ll roll up their sleeves and have fun with it.”

What’s more, Nine has reportedly secured a major property deal for just under $11 million at the Victoria suburb of Mount Eliza on the Mornington Peninsula for the 2026 season of The Block to take place.

Mount Eliza is an affluent bayside suburb mostly home to older families.

It’s known for its beaches, leafy atmosphere, and village feel where diners flock to bustling restaurants, humming cafes, and boutique shops.

The location was purchased from former Aussie racing driver Rusty French and spans 1.35 hectares, and is subdivided into 10 premium lots.

About six of those lots have been secured for the upcoming reno series, with the remaining four either available for short-term lease or sale.

It’s unclear whether the celebrity edition will take place at Mount Eliza in 2026 or whether Nine has reserved the idea for a later season.

Nevertheless, viewers aren’t happy about it.

“Nooooo,” said one person on Instagram, as another person declared the crossover, which emulates the likes of Australian Survivor: All Star and I’m a Celebrity…Get Me Out of Here! Has been “overdone” on Aussie TV.

“Boring,” they said.

Others are brimming with excitement.

“Oh wow, a celeb edition of The Block? Would lose it if Martha and Michael brought their MAFS drama to the build site!” one person said.
