I recently participated in a workshop on Advocating for First Peoples, led by Nathan Tyson, an Aboriginal man, of Anaiwon and Gomeroi heritage in North Western NSW. (This was part of the excellent Out Of The Box mission conference held in July.) Nathan is currently working as Manager, First Peoples Strategy and Engagement, in the Synod of NSW and the ACT of the Uniting Church.
The workshop had two parts. In the first part, we explored what we know about the history and current situation of First Peoples. In the second part, we considered what actions we might take to work with and advocate for First Peoples.
What do we know?
In the first part, Nathan offered us a series of insights into the experience of the First Peoples of Australia, drawing on what we know about the history, customs, and current situation of Aboriginals and Torres Strait Islanders across the continent, and in the associated islands linked to this continent.
The five areas were: the impact of invasion and colonisation — the many massacres that occurred, and the almost complete absence of calling British settlers to account for these massacres — the Doctrine of Discovery and the resulting claim of terra nullius about Australia — the Stolen Generations — and the current push to tell the Truth, listen to the Voice of First Peoples, and establish Treaties with the various nations of the First Peoples.
First, there is the story—now becoming well-known and widespread— of the impact on First Peoples from the invasion and colonization that took place from 1788 onwards. (I use these terms deliberately; describing the British colony as a settlement is far too benign; it ignores much of the harsh reality of what took place.)
The period of invasion and colonisation saw innumerable massacres take place. As well as the thousands of Aboriginal deaths that occurred through these massacres, British invasion also led to the deliberate marginalising of people in many of the Aboriginal nations that existed at that time.
There is a powerful visual symbol of these massacres at The killing times: a massacre map of Australia’s frontier wars | Australia news | The Guardian
The map is interactive. The number of massacres that were perpetrated by ordinary people—not soldiers, not government officials—is truly horrifying.

Associated with this is an observation that provides a second area worthy of note. It is the case that virtually no white persons were charged for the acts of violence and murder that they perpetrated. (The Myall Creek Massacre provides one of the rare exceptions to this claim. See https://www.creativespirits.info/aboriginalculture/history/myall-creek-massacre-1838)
Third, Nathan referred to the rationale that was driving both the colonisation of the continent and the massacre of First Peoples—the Doctrine of Discovery, promulgated in medieval times and driving the expansionary colonisation policies of many European nations, including Britain. It was this Doctrine which formed the foundation of the claim of terra nullius—the notion that the there were no people in the land who were settled in the land.
The Uniting Church in Australia has joined with other churches around the world in repudiating the Doctrine of Discovery. See https://johntsquires.com/2018/08/13/affirming-the-sovereignty-of-first-peoples-undoing-the-doctrine-of-discovery/
Fourth, Nathan noted the issue of the Stole Generations, a blight on the history of Australia since the nineteenth century. This matter was addressed in Bringing Them Home, a highly important report issued in 1997. The commission that produced this report was led by Sir Ron Wilson, a High Court judge who had served as UCA Moderator in Western Australia and then as the fifth national President (1988–1991).
The continuing saga of Aboriginal children being taken from their homes remains with us today, to our national shame. Even in the 21st century, indigenous children continue to be taken from their families. In fact, there are far more Aboriginal children in out-or-home care now, than there were in 1997 when the Bringing Them Home report exposed countless stories of terror and tragedy amongst the Stolen Generations.

The final area canvassed in the first part of the workshop focussed on the theme of Voice. Treaty. Truth. This was the theme for NAIDOC Week 2019. It consists of a call to give Voice to the First Peoples of Australia by establishing a representative body to advise federal law makers; to establish a Treaty with each of the nations that were in the land before the British sent their invading colonisers; and to tell Truth about the history and the present situation of Aboriginal and Torres Strait Islander peoples.

Nathan encouraged all of the workshop participants to learn about First Peoples, their history, their realities, and their aspirations, and to approach First Peoples with an open mind and with a compassionate heart.
What can be done?
In the second part, Nathan then provided a comprehensive set of practical pointers for us to consider. Given what we know about the situation and perspective of our First Peoples, what can we do to support, collaborate with, and advocate for these peoples? Here are the practical steps that Nathan provided for us to consider and adopt:
Put yourself in the shoes of First Peoples and try to walk the journey with them as they experience it
Talk with family and friends about the issues that you hear about, encourage truth telling, stand up against racism
Develop relationships, listen deeply to the needs and aspirations of First Peoples
Respect the right of self-determination of Aboriginal Peoples
Undertake simple advocacy activities to support the needs and aspirations of First People’s (synod, assembly, Common Grace, ANTAR, Amnesty)
Join rallies and marches to show solidarity with First Peoples, eg those advertised by FISTT (Fighting In Solidarity Towards Treaties, a Facebook group)
Pay to undertake a Walking on Country experience with a local organisation
Employ First Peoples in your business, purchase goods from Aboriginal businesses, collaborate in social enterprises and community initiatives
Make your church space available for use by Aboriginal Community, for elders, community, social gatherings
Help with fundraising to support Aboriginal community initiatives
Use the system: help a person to lodge a complaint with agencies such as NSW Ombudsman’s Office, Anti-Discrimination NSW, NSW Office of Fair Trading, Ombudsman for Telecommunication Industry, Energy Industry, Community Legal Services (for civil matters)
There are plenty of practical suggestions in this list. It is worth the effort to start implementing some of them!
