It's Heston Blumenthal week. Heston takes the top 12 contestants on a road trip through regional Victoria; the first stop is the mighty Murray River in Swan Hill.
Nominations. Jason's parting message rattles some of the housemates, in particular Cat and Lawson. Housemates must nominate each other with Priya receiving extra power with her vote.
Working as a team has never been more important or difficult in the challenge apartment, particularly on the communal roof top. The judges are impressed by the completed cafe Mr Zen, as well as the rooftop terrace, so Scotty treats everyone to a party.
Our special guests this week are Speech from the Grammy Award winning band Arrested Development, comedian Judith Lucy, classical virtuoso Katarina Kroslakova and Scott Edgar from band Tripod.
