Artistic creation is often influenced by personal experiences or cultural shifts, while historical and cultural backgrounds provide compelling evidence for exploring the narrative of Australian Indigenous cultural identity. The influence of Aboriginal art continues to expand globally, with its diverse expressions propelling it to new heights. As Australia's foremost multi-disciplinary artist, Archie Moore's work is deeply rooted in the broader context of Australian colonialism, racism, Aboriginal culture, and issues of cultural identity and relationships. Utilizing conceptual art as his medium, Moore delves into the exploration of depicting and understanding Aboriginal culture within contemporary art. This study uses the creative practice of Archie Moore as a case study, where qualitative data is drawn through archives and documents. Here reviews a series of representative Indigenous art practices by Archie Moore, whose conceptual art practices subverted the mainstream narratives of traditional Indigenous art. Through this exploration, the profound significance of Aboriginal art in a postcolonial context is revealed, highlighting its importance in contemporary discourse. This study acknowledges the significant diversity of Aboriginal art and can enhance awareness of the complexity of Aboriginal art and further Aboriginal cultural identities.
