Ten's new panel show Can of Worms got off to a good start with more than 900,000 viewers tuning in for its debut.
The program attracted 930,000 viewers and was the 11th most watched show of Monday evening.
Ten's cooking juggernaut, MasterChef Australia, was the most watched show of the evening with 1.589 million viewers tuning in to watch 34-year-old web designer Billy Law be eliminated in a salt-encrusted guinea fowl and a thyme jus pressure test.
Law was up against lifesaver Hayden Quinn and computer tech support worker Mat Beyer, both 24.
Beyer may have made it through his first pressure test but is expected to be booted off the show on Wednesday night, for breaking MasterChef rules and taking a smartphone into the competition.
Nine's renovation reality show, The Block, secured its highest average audience for the season with 1.471 million, making it the second most popular show of the night.
Seven's local productions also performed well with long-running soap Home and Away and reality show The Amazing Race Australia earning 1.048 million (seventh) and 1.032 million (eighth) viewers respectively.
Following Monday's ratings, Seven announced a second season of its new Melbourne-based drama Winners & Losers, which follows the lives of four friends who won the lottery after being reunited at their high school reunion. Season one (currently airing) has proved a winner, with audiences averaging 1.36 million viewers each week.
Creator Bevan Lee (Packed to the Rafters) said, "I'm delighted we are able to continue exploring the lives of Bec, Frances, Jenny and Sophie in a second series, thanks to the audience embracing our show so enthusiastically."
"And with the season one finale set to turn the girls' world upside down, I'm sure viewers will be eager to see whether the girls' new relationships and challenges make winners of them -- or losers."
Pre-production will commence shortly, with leading ladies Melissa Bergland, Virginia Gay, Zoe Tuckwell-Smith and Melanie Vallejo, and supporting cast Blair McDonough, Tom Wren, Damien Bodie, Stephen Phillips and Denise Scott all set to return to the show.
Foxtel says it was the most popular non-sports program on the pay TV carrier, with its audience up 30 per cent on the premiere of the preceding season and 53 per cent on the average audience for the latest season of the US version.
