After a six-year break, The Block returned to screens in 2010 – and with a bang!

Season 3 of The Block was a memorable for many reasons, the main one being it was the season that beloved host Scott Cam first joined the show.

Watch Scott Cam's Block debut in the video above.

"Having been a builder for 30 odd years, I've seen my fair share of renos but tonight you're going to see eight ordinary people do extraordinary things," a fresh-faced Scotty beamed.

Those eight ordinary people were engaged couple Chez and Brenton, best mates Mark and Duncan, sweethearts Jake and Erin and married couple Neisha and John.

Scotty warned that the couples "better spend their budget wisely" because the Blockheads were renovating four apartments in Sydney's exclusive suburb of Vaucluse.

While Season 3 of The Block gifted us a Scotty Cam debut, it also gave as another first – the first home to pass in come Auction Day.

AROUND THE BLOCK: Two couples fail to make profit at auction and one team's shock exit rocks Season 2

Fan favourites Chez and Brenton were left heartbroken when their property didn't reach its $880,000 reserve and became the first Block home to fail to sell at auction.

Brenton was so distraught he stormed out of the viewing room leaving his fiancée Chez reeling.

"F--k this," he said walking out of the room.

Watch the tense moment in the video below:

Thankfully, Chez and Brenton managed to sell their property outside of auction and made a profit of $90,000.
