The two winners of Wednesday night were Big Brother with Benjamin Norris taking the crown and ABC News with Barack Obama's re-election as US president.
Returning after a four-year hiatus and on a different network, Big Brother was a consistent Top 10 rating show.
Wednesday night's finale was the perfect exit for the Nine Network series after 1.473 million watched Benjamin Norris named the winner of the ninth series.
Openly gay Norris then shocked the audience and the host Sonia Kruger by getting down on one knee and proposing to his partner Ben Williams.
The winner's announcement was the No.1 show followed by the Big Brother Grand Final, which was watched by 1.260 million viewers.
Meanwhile ABC News outgunned its commercial rivals, finishing third with 1.087 million viewers, who tuned in to watch the US election results.
Nine News (1.078 million) was fourth and Seven News (1.033 million) was fifth.
Seven's reality show Surveillance Oz pulled an audience of 1.021 million viewers and Embarrassing Bodies, which immediately followed Big Brother, was seventh with 974,000 viewers.
A Current Affair held up well to be eighth with 962,000 viewers, while Today Tonight failed to make the Top 10.
Big Brother's success relegated Today Tonight (899,000) to 11th spot and Home And Away (847,000) to 13th.
Rounding out the Top 10 were Criminal Minds with 959,000 viewers and Highway Patrol 926,000 viewers.
Network Ten's family show Glee failed to fire, finishing in 21st place with only 473,000 viewers.
