it's time Australians looked at what, and whom, we commemorate

Who is this 'we'? "The past is another country, they do things differently there." That's always true, and it's never truer than when talking about the design of public spaces and the monuments chosen to live in them.

We are all invaders occupying the space someone else once filled. The people who commissioned, sculpted, cast and erected those bronze statues believed they were doing the right thing. Those monuments mattered to them, just as the layout and design of the parks that house the monuments mattered to them, just as the choice of plants the designer chose for his park mattered to him.

If you are angry with those people for their callous disregard for one thing or another, that's for you to correct by adding something new to the public space. Removing someone else's mark on the world is the very definition of censorship, and doing it to a public monument is tantamount to vandalism. Add, don't subtract. Tell your own story, even if it's to make a point of saying why your predecessors were wrong.
