Since Hills announced yesterday that the music quiz show is coming to an end this year, fans have been campaigning to get a star like former Australia's Got Talent judge Red Symons to take over the series.
ABC's head of arts and entertainment Amanda Duthie said that Symons, radio show Dave O'Neil and comedian Wil Anderson are not being considered as replacements because the show wouldn't be the same without Hills and his co-stars Myf Warhurst and Alan Brough.
She told the Herald Sun: "The success of Spicks and Specks has been very much due to the relationship between Adam, Myf Warhurst and Alan Brough. It's not just a format - they are the show.
"They've left very big boots to fill, and we wouldn't attempt to replace the magic."
When he announced the end of the show, Hills said: "We always said we wanted to leave when we were on top and while we were still having fun, and now feels like the right time.
"We are indebted to our loyal fans for giving us seven amazing years on Australian television, and I hope they'll hold the memories of Spicks and Specks close to their hearts."
Warhurst thanked the show's fans on Twitter, saying: "Yes it's true everyone. #SpicksandSpecks ends this year. It's been an amazing experience. Thanks for sharing it with us and supporting us."
Hills wrote that the show had been "a wonderful joyous ride, with two of the best people on the planet beside me, & beautiful people around us."
Spicks and Specks won a Logie award for 'Most Outstanding Light Entertainment' earlier this year.
