In NSW that example would fall under voluntary manslaughter (murder (s18 Crimes Act) plus a defence of extreme provocation s23) which carries up to 25 years of jail (like all manslaughters s24). In the state of Victoria this defence was removed entirely whilst NSW amended the section for the extreme provocation offence where one of the elements is that the conduct must be a serious indictable offence (i.e. an offence that carries 5 or more years). This amendment was largely because there had been instances of non-violent homosexual advances that had resulted in murder and the defence being applicable.
