Other presenters, both publicly and privately, have expressed their dismay after the station took a jab at Triple J for changing the date of its Hottest 100 countdown out of respect for Indigenous Australians.

Radio royalty Mick Molloy and Jane Kennedy recently told listeners they believe Australia Day shouldn't be held on January 26.

"I'm speaking for myself here, but I would like to see Australia Day moved so everyone can enjoy it," Molloy said. "If you want to do it, include everyone. Keep the public holiday, remove the date and everyone can enjoy it together."

The pair also invited ARIA-winning Indigenous artist Dan Sultan onto the airwaves to talk about why January 26 was a sad day for Australia's first peoples.

The comments mean presenters from Triple M's two most prestigious programs, Drive and Breakfast, have now spoken against management's decision to host a countdown on Australia Day.

Molloy and Kennedy are currently hosting Triple M Drive in Melbourne, but in a network first their show will transform into a national drive show come January.

Last week, Breakfast co-host Wil Anderson tweeted that he was "extremely shocked" by the Ozzest 100 announcement.

"[I] have made that clear to management yesterday and will continue to hold and prosecute why I don't think it's a good idea," he wrote. "I was as shocked and disappointed as you would imagine as someone who has vocally and on the record expressed how proud I was of Triple J."

Despite the pushback, Triple M is not backing down on its plans to take a jab at its "hipster" rival. Content head Mike Fitzpatrick has said the network will air the Ozzest 100 as planned in order to "celebrate Aussie artists".

However, the countdown could be in for an upset after Indigenous rapper Briggs urged fans to vote for his hit single January 26. The award-winning track, which also features Dan Sultan, was written in order to educate Australians about Australia Day.
