The first Hockey budget included a succession of significant broken promises. The government has been judged so harshly over the budget that the Prime Minister and the Treasurer are now fighting to hold their jobs after less than 18 months in office.

That’s not an opinion. It’s a fact.

In contrast, Colleen Ryan’s criticism of Sarah Ferguson’s budget interview with Joe Hockey last May on 7.30 is not fact. It’s opinion. More than that, Ryan tries to put herself in the mind of an average viewer. Who on earth is an average viewer when you’re talking about politics?

In Ryan’s opinion “an average viewer would consider that the Treasurer was not treated with sufficient respect” by Ferguson. That is a near-impossible matter to arbitrate in the current sphere of political interviewing.

Richard Carleton’s “blood on your hands” question to Bob Hawke the night he deposed Bill Hayden as Labor leader in 1983 is one of the most celebrated questions in television history. Did Carleton show sufficient respect? By what standards?

Put that question to 10 people in a room and you’ll get an argument, probably on party lines.

Ryan opines that the language in Ferguson’s first question was emotive.

Referring to new taxes in the budget Ferguson asked: “Is it liberating for a politician to decide election promises don’t matter?”

I don’t believe it was emotive, particularly delivered in Ferguson’s trademark deadpan style. We’re both entitled to our opinion.

The question was provocative, which Ryan acknowledges can be acceptable under the ABC’s editorial guidelines, but that too is a matter of opinion.

Ryan also observes that Ferguson is equally tough with all politicians as she was on budget night.

Today’s politicians are obsessive in their attempts to manage the media. There’s an army of minders behind the scenes who would have devoted substantial time and energy planning their media strategy to sell the budget in the best possible light, and minimise its political negatives.

Hockey’s job that night was to sell a politically loaded budget in the best possible light.

Ferguson’s job was to keep Hockey honest and cut through to the core issue at the outset. In this case it was clearly the government’s credibility at the most fundamental level, and the subsequent public backlash over many months (presumably including many average viewers) shows that Ferguson’s questions were absolutely spot on.

The fact is, Ryan was given an impossible task. Or is that just my opinion?

In now asking its interviewers, often in difficult, high-pressure circumstances with limited time, to be second-guessing some future single arbiter on highly subjective benchmarks as they prepare and deliver their questions, the ABC board risks creating a climate of self-censorship, sanitisation and timidity, which would seriously undermine the foundations of the institution’s independence.
