Tasmania abolished provocation as a defence to murder.
In 1998, the Model Criminal Code Officers Committee recommended that the defence of provocation be abolished and that the defence of excessive self-defence not be reintroduced. In 2003, Tasmania became the first state to abolish the defence of provocation. In 2005, Victoria also abolished provocation and made other reforms including clarifying the defence of self-defence to make it more available to battered women who kill, introducing legislative guidance on the relevance of family violence evidence in relation to a defence of self-defence, and reintroducing the partial defence of excessive self-defence.
