Thanks. I've made some small edits.
A geological footnote: the Hawkesbury sandstone around Sydney was laid down in the Triassic, when the sea levels were higher. Because sandstone is compact, there's only a thin soil cover on top, and species like tea trees abound, particularly around the coastal cliffs, where the winds tend to be strong.
