The Block duos race to the finale

It’s been 12 tough weeks for the teams from The Block, as they’ve tirelessly toiled away on their houses.

For Jo & Damo, Alex & Corban, Maree & James and Quinn & Benn, tonight will be the moment of truth as each of their properties goes under the hammer.

Damo, 36, says he’ll be a wreck by the time of the auction! “It’s bad enough auctioning your own home, let alone doing it in front of a million viewers,” he told Woman’s Day

Beauty therapist Quinn has been hard at work despite being five months pregnant.

Hubby Ben, 30, says he’s “unbelievably proud” of her.

But while they may be the underdogs of the competition, but Quinn and Ben love their house and “hope others will too”.

Alex and Corban have been wowing the judges throughout the competition.

“This kind of thing can make or break a relationship, and I can happily say that I respect and love Corban more than ever,” Alex told Woman’s Day.

Whatever happens on auction night, Alex and Corban say they’ve enjoyed their time on The Block.

Maree and James credit their success to their dedicated team of “incredibly loyal” tradies.

While a reality TV competition can be a tough challenge for any relationship, Maree has loved seeing James “leap out of his comfort zone”.

“I have learned that is the male version of me – my perfect match!” Maree says of James.

With $80,000 prize money on the line, it’s sure to be a nailbiting moment for all of the hardworking teams!

The Block finale airs tonight at 7.30pm on TV3

Good luck to all the teams!
