Great success for Ten with Under The Dome (6th – 1,175,000) almost bumping the 3rd last Packed To The Rafters (5th – 1,181,000) out of the lead for 8:30pm. Not so great news for Nine with a most underwhelming Celebrity Apprentice (Challenge: ???; Boardroom: 18th – 653,000) finale. House Rules (1st – 1,474,000) the big winner again with it’s third last show for season one, head and shoulders above an erratic challenge-based The Block Sky High (4th – 1,191,000).
