Sezon 4

The fourth season of The Block premiered on Monday, 20 June 2011 at 7:00 pm on the Nine Network. Host Scott Cam returned from the previous season, with Shelley Craft joining the series as "Challenge Master". Unlike previous series, the fourth season was filmed in Melbourne rather than Sydney, with the four houses to be renovated located in the inner-city suburb of Richmond. The season was ultimately won by Polly Porter and Warwick "Waz" Jones, who were the only couple to sell their property at auction.
