The Block insiders reveal the explosive drama set to hit the new season - as production wraps up on the Mount Eliza shoot

The Block is officially wrapping production this week after an intense 12-week shoot in Melbourne's affluent seaside suburb of Mount Eliza.

And insiders claim Channel Nine could be preparing for one of the franchise's most drama-filled seasons yet, with the series expected to premiere in September.

Daily Mail understands final scenes are now being filmed as host Scott Cam juggles a hectic schedule between The Block and Channel Nine's new reality series Shark!

Sources say Scott has been flying across the country promoting Shark! before returning to Mount Eliza for filming commitments on The Block's crucial final week.

'It's been a huge juggling act,' claims one insider.

'Scotty has basically been bouncing between two major Nine productions at the same time.'

But while the renovations may be near completion, insiders say much of the conversation surrounding Season 22 is already centring on the cast dynamics. 

Particularly the female-driven conflict brewing behind the scenes.

According to insiders, this year's outspoken personalities already have one contestant drawing comparisons to some of The Block's most polarising recent stars.

House 1 contestant Jolene is reportedly emerging as one of the season's most unfiltered voices.

Some sources have claimed she quickly became known for 'saying exactly what she thinks' throughout filming.

'There's always one contestant each year who becomes the person everybody is talking about,' says a source.

'You had Kristy, you had Kylie, you had Alicia! All women who were outspoken, direct and completely unapologetic about it. Jolene definitely falls into that category.'

However, sources insist Jolene was far more aware of how previous Block 'villain edits' have played out than contestants before her.

During filming breaks, insiders claim Jolene spent time watching previous seasons of The Block and closely studying how past contestants were portrayed on-screen. 

'She was absolutely analysing it,' claims one insider.

'She understood exactly how those strong female personalities can be received publicly and was trying to learn from what happened to the women before her.'

Despite that awareness, sources say Jolene still frequently found herself at the centre of tensions throughout production.

'Even knowing the risks, she still naturally says what everybody else is thinking,' says the source. 'And that inevitably creates friction in an environment like The Block.'

The Mount Eliza season has already been described internally as a far more glamorous and emotionally charged version of the franchise.

Contestants have been living off-site together during production rather than directly on the construction site, as seen in previous seasons.

Insiders claim the off-site accommodation arrangement created more opportunities for friendships, alliances and conflicts to spill over once tools were down for the day.

'There was a lot more interaction after hours this year,' says one source.

'That changes the dynamic completely because people don't really get to escape each other.'

While Channel Nine is expected to focus heavily on the stunning coastal builds and luxury finishes this season, insiders say producers also believe the cast chemistry will become one of the major talking points once episodes hit screens later this year.

'The feeling internally is that audiences are going to have very strong opinions about certain contestants,' claims the insider.

'And honestly, that's exactly what The Block has always thrived on.'

Daily Mail has contacted Nine for comment.
