The Society plays a leading role in advocating for the understanding and promotion of history and for the conservation of Western Australia’s built and movable heritage. It does this in a number of ways:
- Participating in public campaigns aiming to save important built heritage;
- Initiating advocacy for the preservation of built heritage sites and movable heritage collections through submissions to the government and its agencies;
- Active membership of the Federation of Australian Historical Societies and its network of national peak bodies such as the International Council of Monuments and Sites Australia, Australian Council of National Trusts and Museums Australia.
- Membership of like-minded Western Australian peak organisations with an interest in promoting history and heritage such as Museums Australia (WA) and the History Council of WA.
- Responding to requests from the Heritage Council of WA relating to proposed entries into the State Heritage Register;
- Supporting its Affiliated Historical Societies’ submissions advocating for the preservation of their local built and movable heritage.
