Scott Cam has revealed the one thing that makes him nervous when filming The Block.

The TV host appeared on Triple M Breakfast on Thursday in the run-up to the 21st season’s premiere.

When asked about how he feels on auction day at the end of each series, Scott candidly admitted that his nerves are through the roof.

‘Look, I don’t get nervous ever,’ the 62-year-old confessed to radio host Aaron ‘Woodsy’ Woods.

‘And then on auction day, I wake up feeling sick to my stomach. I’m about to have a spew.’

Scott went on to say that it made him nervous to watch the auction when all of the participants had put in so much hard work and deserved to make ‘some coin’.

‘We don’t want anyone to fail. We want everyone to make a quid. They’ve worked really hard,’ he said.

‘We want them to make some coin on the day so I’m really nervous for them. And sometimes they don’t make any money.’

He added: ‘It’s a really tough day in the office when I’m looking at someone that’s worked for three months and made five grand.’

The series, which wrapped filming on June 1, is set to premiere slightly earlier than usual, hitting screens on July 27.

While fans have come to expect fiery feuds and over-the-top drama, insiders say this season is shaping up to be very different.

‘There’s actually much less conflict this year,’ one well-placed insider said.

‘But that doesn’t mean it’s boring. There’s a charm and warmth to this season that will surprise long-term fans.’

It comes as Nine unveiled its first look at the new series, in a teaser clip that aired during their State Of Origin game two coverage.

The clip showed hosts Scott Cam and Shelley Craft driving Block-themed big rigs in a convoy to the new locale.

‘This year, we’ve packed up the whole shebang, and we’re heading for somewhere special,’ Scott says in the clip.

‘That’s right Australia, I’ve found a cracker of a country town, you’re gonna love and we’re rolling in for a truckload of fun.’

The tongue-in-cheek preview also gives fans a first look at the 2025 Block teams – Emma and Ben, Han and Can, Robbie and Matt, Alicia and Sonny, and Britt and Taz.

The teams were shown excitedly jumping out of Scott’s big rig to promote what is promised to be the best Block season yet.

News Corp reported in December that Nine dropped almost $10million to acquire the land that has been subdivided into five separate lots.

The publication reported that the Nine-owned company Micjoy Pty Ltd took ownership of the parcel of land for $9,445,801.00.

The figure is on par with previous Block purchases, with Micjoy dropping $10million on the notorious Gatwick Hotel in Melbourne for the Block’s 2017 season.
