- Dispossession: The colonisation of Swan River Colony led to the dispossession in traditional lands and resources of the local Aboriginal people, including the Noongar people. This resulted significant disruption of their way of life, economic activities, and cultural practices.
- Disruption of society and culture: the arrival of settlers disrupted traditional Aboriginal societies and cultural practices. The colonisers introduced new diseases, and Aboriginal traditions and belief system underwent significant changes.
- Conflict and violence: The colonisation led to numerous conflict and violent encounters between the Aboriginal people and colonists, resulting in loss of life, displacement and trauma for Aboriginal communities.
- Loss of spiritual connection: The colonisation disrupted Aboriginal people's spiritual connection to their land, as it was deeply integrated into their beliefs, ceremonies and practices.
- Marginalisation: The colonisation caused the marginalisation and subordination of Aboriginal people, resulting in social, economic and political disadvantages that persisted for generations.
- Assimilation and loss of identity: colonial policies often aimed to assimilate Aboriginal people into colonial society, leading to a loss of cultural identity, language and traditions.
- Disease: introduced by European colonisers had devastating effects on Aboriginal populations, further reducing their numbers and increasing their vulnerability.
- Environmental destruction: Colonisation led to the modification and degradation of the natural environment, which severely impacted Aboriginal peoples' way of life, as their sustenance and cultural practices were closely tied to the land.
- Disruption of traditional trade routes: The colonisation disrupted traditional trade routes and economic networks that Aboriginal people had with other Indigenous communities.
