The fifth season of Australian reality television series The Block, titled The Block 2012, aired on the Nine Network.

Both Scott Cam returned as host and Shelley Craft as "Challenge Master".

The season premiered on Monday, 16 April 2012 at 7:00 pm.

Like the previous season, this season was filmed in Melbourne, with the four houses to be renovated located in the inner-city suburb of South Melbourne at 401 Dorcas Street.

At first, this season wasn't to air in New Zealand,[1][2] but has now been picked up by TV3 (the channel that broadcasts the New Zealand adaption of the program).
