Watch The Block 2020 trailer and take a look back at the season. Post continues below.

This year the five teams were tasked with bringing five family houses back to life in the bayside Melbourne suburb of Brighton.

ButThe Blockisn't just about building homes. It's also about all the tension and competition that comes with it.

Ahead of tonight's finale, we've complied all the behind-the-scenes gossip you need to know in one place.

There's "fear" that all five houses won't sell.

We finally made it to finale night. But it seems not everyone is confident all five houses will sell.

Speaking to Nine ,the show's executive producer Julian Cress explained that there's a chance that not all the houses will sell due to Melbourne's plummeting auction clearance rates.

"Clearance rates are currently running in the sort of 60th percentile in Melbourne. That would suggest that we’re on track to sell three out of five of the houses," Cress toldNine.

"My nervousness and fear is obviously that I want to sell five out of five, because I want all the contestants to do really well."

"So, getting to sell all five, on one day, in this environment is what’s keeping me up at night, but the houses are, I think, the best homes that we’ve ever taken to auction."

Host Scott Cam also explained that he's "hoping for the best" given the current market.

"Auction day is one of the most nervous days of my year. I think we are the only show on television that has absolutely no control over the finale. We are just sitting there hoping for the best in the COVID-19 property market," he said.

"They really are the best houses we have done onThe Block, four, five and six-bedroom family homes. All the Blockheads have sacrificed so much – this year more than ever. We always want them to walk away with a life-changing amount of money, but we just don’t know what will happen on Sunday."

It turns out a lot of the work goes on behind the scenes.

There's no doubtThe Blockis hard work, but it turns out most of it is actually done when the cameras stop filming.

"During the day, it's very hard when you have 30 people in one room, and that's when project managing comes in, and as soon as they leave, we're up for the next 12, 13, 14 hours a night, doing it all behind the scenes," George told the Daily Mail.

"But in saying that, without a good team, you can't do the show. It's a two-way street."

Speaking of work, couple Jimmy and Tam told the publication that each team works just as hard as their tradesmen.

"Believe it or not, we actually do a lot of work. We are nonstop. The times you see us just holding a coffee or whatever is literally our five minutes of downtime when we can get it," said Jimmy.

"But other than that whether Tam's out shopping or I was on the tools just getting the job done, we were working the whole time. But we do rely on our tradies a lot."

The contestants have never met the judges.

Every week we tune in to watch judges Neale Whitaker, Shaynna Blaze and Darren Palmer score each of the contestants' room reveals (arguably the best bit of the whole show).

But it turns out the contestants have actually never met the judges.

"We never actually got to meet the judges because they didn't want bias, but in terms of the foremen, we got along well," Sarah told the Daily Mail.

Luke and Jasmin respond to the copying allegations.

Earlier this season, contestants Luke and Jasmin were accused of copying one of their bedroom designs, which later helped them win the https://www.mamamia.com.au/the-block-2020-double-room-reveal/ double room reveal.

During the episode, judge Shaynna Blaze presented the couple with a picture of a children's bedroom which looked a lot like the room they had just designed.

The room in question was one from anInside Outmagazine photoshoot, which was created by The Designory and features on their website.

Jasmin explained that the photoshoot was simply the "inspiration" for their room. But Shaynna wasn't having it.

"I showed everyone that picture while we were filming, saying it was my inspo. It wasn’t a secret," said Jasmin.

"You’re calling it inspiration. Inspiration is one thing. Completely taking someone’s idea and making it your own is another," replied Shaynna.

"We’re in a competition, and you won a room where you make money. You haven’t changed it up enough."

After the episode aired, Luke and Jasmine posted a statement on Instagram, saying it isn't against the rules to take inspiration from other places.

"Okay.... so our side of the copygate saga," they began the post.

"We were just working happily on our kitchen when Shaynna popped in to give us a slap on the wrist for copying. Our faces said it all, we were in shock. All week we were showing our moodboard which featured the room from the @thedesignory (among other images). We were open about using it and believed it was all above board."

They went on to explain that previous Block contestants in 2017 were also accused of copying their kids' room.

"They got a perfect score and won the room. Then were later accused of copying by other contestants. They were cleared of any wrong doing byThe Block, Scotty and judges. At the time, a Channel 9 spokesperson stated 'The only rule is that contestants don’t enlist the help of a professional interior designer. There is no limit on the boundaries to which contestants can take an inspiration image and draw on latest trends for their rooms.'

"So this is our understanding of the show ‘rules’ with regards to copying. Rules, which we haven’t broken."

The couple added that they know other contestants this season have copied images when designing their rooms.

"We are all everyday Aussies, none of us experts in design and if we need the help of Pinterest and Instagram then we are allowed to use it freely within show rules, as much or as little as we like."
