One of Australia’s longest-running reality television hits is facing an unexpected renovation controversy this season — and it has nothing to do with tiles, kitchens or contestants blowing their budgets.

Viewers of The Block have been taking aim at Channel Nine’s increased use of artificial intelligence throughout the 2026 season, with AI-generated video sequences and music becoming a regular feature of the show’s distinctive editing style.

The technology appeared almost immediately when season 22 premiered in August.

Contestants discussing their “spirit animals” were digitally transformed into animals, while another exaggerated AI sequence showed aliens looking down on the enormous Block headquarters.

Since then, the experiments have continued.

Artificial intelligence has been used to change contestants’ clothing, place them in imaginary environments, transform them into animals and create deliberately bizarre cutaways designed to amplify jokes made during the program.

The soundtrack has changed too.

The production team has introduced original AI-generated jingles alongside the conventional music library that has long been a hallmark of the show.

For some viewers, it is a harmless extension of The Block’s famously playful editing.

For others, it is becoming one of the most distracting elements of the entire season.

Recent episode triggers another backlash

The criticism intensified again following Sunday’s episode, when the production used AI sequences during several relatively ordinary moments involving the contestants.

When cattle station manager Adam Wagner was described as being particularly sociable around the worksite, viewers were shown an artificial sequence depicting him dancing under nightclub lights.

Another segment involving personal trainer Tayla Peroomal and plans for a margarita machine was turned into an elaborate nightclub-style visual joke.

Other recent AI cutaways have included exaggerated versions of judges and contestants in scenes that never actually occurred.

The intention is obvious: take a passing comment or personality trait and turn it into a visual punchline.

But the frequency of those moments has become the problem for some longtime fans.

Complaints posted across Facebook, Reddit and other social platforms have described the effects as tacky, embarrassing, unnecessary and disruptive to the flow of the renovation competition.

Some viewers have particularly objected to the AI-generated music, arguing that the show’s soundtrack traditionally benefited from carefully chosen commercial songs and the work of human artists.

Calls for Nine to “pay local artists” instead of generating novelty tracks with AI have become part of the backlash.

Others have defended the experiment, saying the deliberately strange graphics suit the show’s sense of humour and should not be taken too seriously.

The reaction is therefore not unanimous.

But the volume of criticism has become significant enough that the show’s producers have publicly explained why they are using the technology.

The Block’s producer says AI is not replacing the show

Post-production executive producer and co-creator David Barbour has defended the decision to bring generative AI into the editing suite.

He says The Block has survived for more than two decades partly because it has continually experimented with the way stories are presented.

According to Barbour, AI is simply the newest addition to a production toolkit that has always included unusual sound effects, graphics, freeze frames, music cues and exaggerated visual jokes.

He maintains that the fundamentals of the program have not changed.

The contestants are still completing real renovations under extreme deadlines, the emotional reactions are real and the competition itself remains at the centre of the series.

AI, he argues, gives editors more ways to exaggerate moments for comedy that previously might have required more complicated or expensive production techniques.

Barbour has also confirmed that artificial intelligence is being used to generate original music for particular scenes.

The show has not abandoned its traditional music library, but AI makes it possible for editors to produce highly specific novelty songs matched to an individual contestant or joke.

For the production team, that degree of customisation is part of the appeal.

For critics, it is exactly what makes the new season feel different.

The argument is partly about authenticity

Reality television has never been a documentary in the strictest sense.

Editors have always shaped footage through music, reaction shots, timing and visual effects.

The Block in particular has spent years using playful post-production to make relatively mundane renovation moments more entertaining.

A contestant dropping a tool might receive a dramatic sound effect. An argument could be accompanied by exaggerated music. A joke made during an interview might trigger an unrelated movie clip or graphic.

Generative AI changes the equation because editors can now create footage showing a recognisable contestant apparently doing something that never happened.

Even when the audience understands it is obviously a joke, the visual itself can look more like fabricated footage than a traditional cartoon or graphic overlay.

That has prompted some viewers to question where playful editing ends and artificially manufactured characterisation begins.

If a contestant is shown as lazy, ridiculous, glamorous or menacing through an AI-generated sequence, the effect may influence how the audience perceives that person even though the scene is entirely fictional.

That issue is not unique to The Block.

Television producers around the world are experimenting with generative AI because it can produce images, animation and audio far faster than older production methods.

The technology therefore creates both an opportunity and a new editorial responsibility.

The more convincing generated footage becomes, the more important it may be for audiences to understand when they are watching reality and when they are watching a visual joke invented in post-production.

Contestants have also used AI for design inspiration

The debate extends beyond editing.

Contestants on the 2026 series have also been given access to artificial intelligence as a tool for researching and visualising renovation ideas as part of a promotional partnership involving Google.

That prompted another criticism from some fans: whether contestants equipped with AI-generated room concepts were receiving an advantage unavailable to teams from earlier seasons.

Several of this year’s Blockheads have rejected suggestions that the technology makes the competition significantly easier.

Chantel and Wyatt said AI could produce a good-looking room concept but rarely created something they could simply reproduce.

Contestants remain constrained by budgets, available products, construction rules, time and the practical realities of getting trades and materials onto site.

Chantel compared AI inspiration with previous contestants using tools such as Pinterest to research interiors.

Other teams said they barely used it for design work.

That distinction is important.

Generating an image of an expensive designer bedroom takes seconds. Actually constructing one within a weekly Block budget and deadline is a completely different challenge.

The technology can provide inspiration, but it cannot waterproof a bathroom, install cabinetry or persuade an exhausted tradesperson to work until midnight.

Why the backlash matters for Nine

The Block has endured because its formula combines several different audiences.

Some viewers watch for renovation ideas. Others follow the contestants and interpersonal drama. Some are interested in real estate, while others enjoy the elaborate editing and humour.

Barbour has pointed to the unusually broad age range of the audience, stretching from children to grandparents.

That diversity also makes a dramatic production change risky.

Generative AI remains culturally divisive.

Supporters see it as an increasingly normal creative technology capable of expanding what small production teams can achieve.

Critics associate it with job losses, imitation of artists’ work and cheap-looking content flooding social media.

Those attitudes inevitably follow the technology onto television.

When AI appears prominently on a program watched by a mainstream audience, viewers are not simply judging whether an individual joke is funny.

They are also bringing their wider opinions about artificial intelligence into the reaction.

The music debate demonstrates that clearly.

To producers, an AI-generated song can be a perfectly tailored comedy cue.

To some musicians and viewers, it represents a job that could have gone to a songwriter or Australian artist.

Both interpretations can exist at the same time.

Not everyone wants the old Block back

It would nevertheless be misleading to suggest the entire audience is rejecting the experiment.

Some viewers have said the AI transformations make them laugh and fit naturally with the series’ deliberately over-the-top editing.

Others simply do not care how a five-second comedy sequence was produced.

Generative effects may also become less noticeable as audiences grow more accustomed to seeing them in advertising, television and social media.

Barbour appears willing to accept the initial discomfort.

His position is that every creative change surprises some viewers and that The Block cannot remain fresh by editing the program exactly as it did years ago.

The production therefore shows no indication that it intends to abandon AI because of the complaints.

That means viewers irritated by the digital animals, artificial songs and fabricated fantasy sequences may be seeing plenty more before the season ends.

The real test will be whether AI serves the story

The most useful distinction may ultimately be less about whether AI should be allowed on television and more about whether each use improves what viewers are watching.

Technology that helps explain a design, create a genuinely funny joke or communicate something visually may be embraced.

Technology inserted simply because it is new can quickly become irritating.

That is the balancing act now confronting The Block’s editing team.

After 22 seasons, experimentation is one reason the series has remained part of Australian prime-time television.

But the program’s enduring appeal also comes from something artificial intelligence cannot manufacture: watching real people attempt difficult renovations while dealing with real money, real deadlines and real pressure.

Nine says AI is only enhancing that story.

A vocal group of viewers thinks it is beginning to get in the way.

Whether audiences eventually accept the change may depend on how often the producers resist the temptation to use their newest tool simply because they can.
