You have written about the "average Australian". This is silly. Even though people (and journalists to their disgrace) speak of the so-called "average Australian", there is no such person. What does YOUR average Australian look like? Is YOUR "average Australian" male or female? Is YOUR "average Australian" short or tall? Is YOUR "average Australian" young or old? Is YOUR "average Australian" earning $15,000 or $1,500,000? Is YOUR average Australian a Jew, a Christian, a Muslim or an atheist? Please don't use this silly expression: "average Australian".
The trouble with the "average Australian" is that the moment you look closely, the person vanishes. An average is a sum divided by a number. It can tell you that the average household has, say, 1.8 children, but it cannot show you a family with 1.8 children, because no such family exists. The "average Australian" is a statistic wearing a hat, and your reader sees straight through it.
Worse, the phrase is usually a trick, whether the writer means it or not. "The average Australian wants" almost always turns out to mean "I want, and I am hoping you will assume everyone agrees with me." It dresses up one person's opinion as the settled view of the whole country. That is not reporting. That is smuggling.
So when you feel the phrase coming, do the honest thing instead: get specific. If you have figures, name them and name their source: "Bureau of Statistics figures show the typical full-time wage is X." If you have a real person, put them on the page, with a name and an age and a suburb. A single real plumber from Penrith is worth a thousand "average Australians", because the reader can believe in the plumber.
Real people and real numbers. Leave the average Australian where you found him, which is nowhere.
