The return of Offspring has given Network Ten a cause for celebration after the station landed two prime time shows in the top 10.
The launch of the fifth season of Offspring was eighth with 931,000 viewers and reality series MasterChef was 10th with 889,000 viewers.
Ten has struggled for top 10 placings all year on OzTAM's overnight ratings which makes Wednesday's result a major win for the network.
The double of MasterChef-Offspring double, which ran back-to-back on Wednesday, shows viewers did not switch channels en masse and gives Ten hope it can build its audience.
The success of MasterChef and Offspring kept the Nine Network's US sitcom The Big Bang Theory (repeat) and the Seven Network's US drama series The Blacklist out of the top 10. They finished 11th and 13th respectively.
Seven News won the evening with 1.194 million viewers followed by Nine News (1.151 million) and a first run episode of The Big Bang Theory (1.131 million).
Comedian Chris Lilley's new ABC comedy series Jonah From Tonga is sinking at a quick rate.
It launched last week in 24th spot with 414,000 and the second episode on Wednesday plummeted to 37th with 287,000 viewers.
