It is a bit difficult to compare thirteenth century England with nineteenth century Australia, for a start, nineteenth century records are pretty much complete. But there are some parallels that can be drawn.
A significant part of the popularity of Robin Hood (if he even existed!) is because he was seen as a champion of an oppressed part of the population (Saxons, especially their upper class who lost out badly in 1066).
Similarly, a lot of the popularity of Kelly can is because he could be seen as a champion of the oppressed Catholic Irish. In many respects these were in the same position as Muslims in contemporary Australia. (It was only a few years after an Irish assassin had tried to murder Prince Alfred in Sydney.)
But the popularity of any national "heroes" has little to do with what they were really like. Consider for example that Australia's most popular national song is about a suicidal stock thief.
It all comes down to "Don't let the facts get in the way of a good story" - but try to remember it's only a story.
