The Block Triple Threat final broke through the two million mark as celebrity pair Darren and Deanne Jolly took home $935,000 from the final auction.
The winner presentation got an average audience of 2.03 million across the five metro markets for Nine according to the preliminary OzTAM overnight figures.
The finale was broken into the grand final, the auction, and the winner's presentation.
The auction itself took home an average audience of 1.97 million viewers while the grand final program attracted 1.64 million sets of eyeballs.
However, all three presentations were down on last year's series finale ranging from 7% to13% as ratings for all channels are broadly down this year against last year.
Seven's best non-news program for the night was Home and Away, which brought in 784,000 viewers, while its news presentation brought in one million.
The Block dominated across all key demographics, and translated to 35.1% share for the Nine network, with 28.4 points drawn from the main channel.
In comparison, the Seven network brought home a 26.8% share, with its main channel contributing 18.5 points.
Meanwhile the ABC and the Ten Network tied for the evening, with a 16% share each.
