Every Australian state and the commonwealth have abolished the death penalty. Queensland as far back as 1922. The last execution (hanging was Ryan in 67 and some believe it was undeserved. Australia has signed the Second Optional Protocol to the International Covenant on Civil and Political Rights, which commits Australia to the abolition of the death penalty. So no more death penalty.
There most certainly is no popular support for the death penalty in Australia. There may be disgusting acts of brutality that cause people to say the perpetrator(s) deserve to die, but few want the State to return to murder even of murderers. That would make the State no better than murderers, no better than you.
