So I am presuming you do not like the Islamic presence in Australia?
i'd try arguing with you but if reality and your reality are two different things and what you showed are the minority of Islam. "Islamic Extremists" make up the minority of aproximately maybe .01% of the religion. You shouldnt generalize a whole community amongst the assumption that everybody follows these Extremists and are these extremists. Islam has 1.6 or something billion members but you focus on not on the peaceful 99.9% but that small bad percent. In life everything has its faults and bad parts. There is basically no single thing without a "flaw". please focus on these and i hope this changed your mind.
