The season 14 premiere of reality home improvement program, Nine's The Block, has taken out the top spot in all key demographics overnight, drawing in an audience of 1.16 million.
Last night's episode, which sees five teams of renovators, aka The Blockheads, face off as they renovate St Kilda’s historic Gatwick Hotel, improved on the 2017 premiere, which attracted an average metro audience of 1.12 million.
It was also the show's highest launch since 2014, with a national average audience of 1.57m.
Seven's Little Big Shots also returned for its second season overnight, coming second behind The Block in the primetime slot, with an audience of 963,000, losing 600,000 viewers and down 42% compared to its series debut last year.
Over on Ten, it was the long-awaited return of Russell Coight's All Aussie Adventures in the primetime slot, drawing in an audience of 881,000.
The comedy program that stars Glenn Robbins as the titular Russell Coight, was back for its third season after going off the air in 2002.
The show reached a national audience of 1.34m viewers, boosted by strong regional viewership.
Ten's second comedy series premiere, Street Smart, didn't fare well, debuting to an audience of only 365,000 metro viewers.
Nine's strong performances from The Block and its nightly news led the channel to victory in the overnight main channel share battle, taking a 24.2% share.
Seven came in second with a 19.5% share, while Ten fell below double digits, recording only 8%.
Below is a breakdown of TV ratings performance, across all the key demographics in commercial share, supplied by Nine.
