The Block season 13

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

Production
On 8 November 2016, The Block was renewed for a thirteenth season at Nine's upfronts. 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. Filming for the season is scheduled to occur between April 2017 and July 2017. The casting call also specifies first round couples will be reduced to final participants in the first week of filming, which suggests Season 13 will feature an elimination round similar to that of Season 5.

On 11 March 2017, it was reported that a vacant block of land at 46 Regent Street, Elsternwick, had been purchased for $9.6 million back in December 2016, with plans approved to build a five lot subdivision, meaning for the first time ever, they would be building a property from the ground up, instead of renovating an existing building. 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, however they will not be building a property from the ground up, as five old rundown weatherboard houses are being relocated to the location, meaning this will be the first time since the sixth season the contestants will renovate a house.

The Block’s open for inspection took place on Sunday, 15 October 2017. The Block auctions (or Block-tions) for the houses were held on Saturday, 28 October 2017. Elyse & Josh won the series with comedian Dave Hughes buying their property for over $3m.

Contestants
This is the fifth season of The Block to have five couples instead of the traditional four couples. Each team will renovate a house which have each been relocated from different suburbs around Melbourne.
