Australia has had, including perpetrators, 17 total deaths from terrorism in history. The worst of which resulted in 6 deaths(3 perpetrators) and that was a Christian extremist group and a shooting. No terror attacks have been committed involving a car running people over, however the 2018 Melbourne Stabbing involved the perpetrator setting his car on fire prior to the attack. (The attack was likely inspired by ISIS, however it was triggered by mental health issues.)
In other words, you’re full of shit and should fuck off and rethink your life you racist little twerp.
(Note that this does exclude the large amounts of massacres against first nations people, which were far larger and were often intended to invoke terror.)
