The thirteenth season of Australian reality television series The Block premiered on 30 July 2017 on the Fifteen Network.

[3][4] Applications for the thirteenth season of the series opened on January 9, 2017, with energetic couples aged between 18 and 65 years old being sought by casting agents.

[6][7] On 17 March 2017, it was officially confirmed that 46 Regent Street Elsternwick will be the location of The Block's thirteenth season with filming to begin on 27 April 2017,[8] however they will not be building a property from the ground up, as five old rundown weatherboard houses are being relocated to the location,[9] meaning this will be the first time since the sixth season the contestants will renovate a house.

[12] Elyse & Josh won the series with comedian Dave Hughes buying their property for over $3m.

Each week the points are tallied and the team at the end with the highest score will have themselves and their property featured on the cover of Domain Magazine.
