Did Australia already have its own Chain Home radar network?

Australia developed radar, but not that early; the Sydney fleet base would likely accelerate an equivalent system.

A viewer asks whether Australia historically possessed its own version of Britain's Chain Home system. Australia did establish radar, but not an equivalent network at such an early date. The enlarged fleet base creates a stronger reason to begin that development sooner. This separates Australia's real wartime radar effort from the counterfactual claim that a strategic Sydney would accelerate it.
