And with Melbourne couple Pete and Courtney still reeling from not being chosen for the early room reveal, Tim and Mat found themselves in the firing line during Wednesday night's episode.
WATCH: Pete and Courtney are out for revenge after not being chosen for early room reveal
As part of a sneaky plan to make Tim and Mat's job as difficult as possible, Pete and Courtney decided to tile the floor right outside the bedroom the brothers were working on for the early room reveal, meaning they wouldn't have access to their room.
“Yeah, wrong decision. Us being in the entry, for them to access Hallie's room on the last day... Whereas if we'd been picked, it's likely it would have been tiled the day before, so that could actually shoot them in the foot,” explained Pete, 32.
Crafty Courtney, 31, admitted she and Pete were “disappointed” they hadn't been chosen for the early room reveal, but added they had “a good plan” in place.
She then told the boys that they were about to start tiling the floor outside the bedroom, with Tim calling it a “low blow”.

“We are going to be tiling in the entry because we haven't been picked for the early room reveal,” Pete confessed.
Courtney added: “The guys aren't going to be able to walk through there, so, soz, guys.”
Tim, 32, was furious they had decided to tile their entryway when he and Mat, 27, were on a tight deadline, and thought it was unnecessary.
“All the other entries have been tiled on the last day. If you're going to tile while I try to complete a room, when you don't need to, you'll be tiling it a few times, mate, because I'm going to step right on it,” he fumed.

But Courtney didn't care about their threats: “We're going to be here to tell them to bugger off.”
Pete declared the entry was “closed for business”, as Courtney got to work taping off access to the entryway.
With no other options, Tim and Mat were forced to go in and out of the window to finish off their room.
