The right of self defence does apply in Australian law>>>>>>>>>>>>>>>>>>>
Yes it does:
Here is the self defense test:
“The question to be asked in the end is quite simple. It is whether the accused believed upon reasonable grounds that it was necessary in self-defence to do what he did. If he had that belief and there were reasonable grounds for it, or if the jury is left in reasonable doubt about the matter, then he is entitled to an acquittal. Stated in this form, the question is one of general application and is not limited to cases of homicide.

Mr Morrison, your knee-jerk reaction won't serve you well when it comes to the next election.
