Karl Stefanovic has answered Anthony Albanese, and it took him one line.

"Just a reminder, I did an interview," the sacked Today host said in the opening of his latest podcast episode. "And he lied to the country, and still has his job."

The Prime Minister couldn't help himself, wading into Stefanovic's exit from Nine, turning one broadcaster's sacking into a warning for anyone who strays from the approved script.

"You go down that road, and you go further and further out on the edges of what is mainstream political debate in this country, and you know, I think that can have an impact," Albanese said.

Stefanovic clearly enjoyed the attention. "To my number one fan, Albo, he wanted in on this action," he told his audience, before landing the counterpunch: "I suppose it depends on who's defining political debate, Albo, don't you think?"

Who gets to define the mainstream

Stefanovic's offence, on the record, is an interview. He asked questions of a guest Channel Nine didn't approve of, on The Karl Stefanovic Show, a podcast he owns and runs himself, and it cost him a 21 year career at the network.

The Prime Minister looked at that outcome and reached for the word "edges," which is exactly how the political class protects itself. Someone has to draw the line around acceptable debate, and the people drawing it always seem to put themselves comfortably inside it. And Karl's charge landed because the country has heard it before.

Pauline Hanson has built an entire campaign around it, One Nation's Fire the Liar push, which has spent weeks cataloguing the promises Albanese made to win office and then walked away from. A prime minister with that record decided a breakfast host's interview was the real threat to public debate. Stefanovic said it to an audience no network can take off the air, and the line is travelling because Australians reached the same verdict long ago.

The comeback rolls on

Karl delivered the line in his first episode since leaving Nine, a sit down with Piers Morgan. Behind the scenes his next chapter is already taking shape, with Kyle Sandilands registering the Kyle and Karl domains that point to a venture between the pair.

The audience answered the question for him

The weeks since have settled the argument on the only measure that counts. Karl Stefanovic's first podcast episode outdrew Today on the same day, 320,000 views against 268,000 viewers, and his channel has kept climbing while the program he was removed from keeps sliding. Anthony Albanese warned about the edges of acceptable debate. The country went to the edges and took the ratings with it.

The same fight is running in Britain

Australia is not doing this alone. In Scotland a university worker was charged over a social media post after Police Scotland first found no crime had been committed and then reversed itself under public pressure. Different country, different facts, same underlying question: somebody decides where legitimate speech stops, and that somebody is rarely the person doing the speaking.

For readers the practical stake is simple enough. If a 21 year career can end over which guest a broadcaster books, the range of questions anyone still employed is willing to ask gets narrower, and the narrowing happens quietly.

One man lost his job over an interview. The other kept the top job in the country, and Stefanovic's question now hangs over him: who defines political debate in Australia? On current form, the man who broke his word to the country thinks the answer is him.
