Many constitutions add a higher, supernatural note by invoking the blessing of a deity.
Apart from theological invocations, most constitutional preambles go beyond a historical narrative to state the democratic and libertarian principles or civic values upon which the polity is founded, the specifics of which are usually reflected in constitutionally mandated democratic government and constitutionally protected rights and freedoms. Since the preamble is not prescriptive, this provision presents no legal barrier to abolition of the monarchy. However, for cosmetic reasons the advent of an Australian republic would require amendment of the preamble since it would look odd, to say the least, for the preamble to an Australian republican Constitution to assert that the Commonwealth was a federation under the British Crown. Two proposed amendments often debated are amendments pursuant to Aboriginal reconciliation and some preambular recognition of fundamental political principles or core civic values. There are strong arguments in favour of constitutional preambular recognition of the prior occupation of Australia by Aborigines and Torres Strait Islanders and of their status as Australia's indigenous peoples.
