Scott Cam (host) and Shelley Craft (Challenge Master) returned from the previous season, as did the three judges: Neale Whitaker, Shaynna Blaze and Darren Palmer.

The Block is located at 27 Darling Street in South Yarra which will be transformed into four north-facing townhouses – some able to enjoy city views from upper levels.

[1] Darren and Deanne Jolly from former The Block: Glasshouse are back to challenge former fan favourites Bec and George Douros and Perth's Kim Owen and Matt Di Costa for one spot for returning players in the 2015 competition.

Six teams of new players will contest a number of challenges, before being whittled down to a final three, who will then go on to renovate an apartment block in South Yarra, with the surviving fan favourite couple.

The Block-Open House is a new format (replacing unlocked) shown once a week which shows former contestants fixing and/or renovating rooms and areas of peoples home into modern looks.
