Background
Four native title applications involve overlapping claims to sea country in the Torres Strait region: the Torres Strait Regional Seas Claim (Part C and Part D), the Wuthathi People Sea Claim, and the Kuuku Ya’u, Uutaalnganu and Umpila Peoples Sea Claim. The applicants sought to partition some claims—removing non-overlapping areas to allow those parts to proceed separately to consent determination—while hearing overlapping areas together. The State of Queensland and Commonwealth were respondents.
Justice Mortimer CJ rejected this fragmented approach after a case management hearing on 25 May 2026. The court noted that all four claims involve sea country with shared or adjacent overlapping boundaries and that evidence in one proceeding would likely be relevant to others.
The Court’s Holding
The court ordered all four proceedings to be heard and determined together, without partitioning. Justice Mortimer CJ emphasized that native title to sea country requires holistic consideration of how traditional law and custom allocated title before sovereignty and how it has passed down to present claimants. She stressed that a fragmented approach would deprive the court of critical perspectives on the complex relationships between mainland and island peoples and their seafaring traditions across the region.
The court rejected separate questions and rejected any attempt to program matters through to final resolution at present. The court directed that further sea country claims over the disputed areas must be filed by 12 October 2026. Two additional related proceedings (the Torres Strait Regional Seas Claim Part B and the three Kaurareg claims) were ordered to show cause by 12 October 2026 why they should not also be heard and determined together with the four claims, unless they reach negotiated agreement by that date.
The four claims are scheduled for two tranches of hearing: 5 days commencing 9 November 2026 (hearing at Mer, Erub, Lockhart River, Bamaga, and Cairns) and 12 days commencing 3 May 2027 (hearing at Sir Charles Hardy Islands, Raine Island, Horn Island, and Cairns). The proceedings remain in intensive case management with ongoing mediation.
Key Takeaways
- Case management efficiency in native title claims may require consolidating overlapping claims even where parties propose partitioning and fragmented resolution
- Courts must consider the entire evidentiary landscape and regional context when claims involve complex questions of traditional law and custom across dispersed island and mainland communities
- Partitioning sea country claims risks artificial segmentation that obscures the holistic nature of indigenous title systems and relationships between groups
- Consent determinations in adjacent areas raise forensic difficulties when compared to disputed areas, supporting consolidated hearing
Why It Matters
This decision reinforces established principles from Akiba (2010) that sea country native title claims require consideration of the whole picture rather than artificial divisions. For the Torres Strait region, it ensures that complex questions about how different island communities and mainland peoples traditionally held and transmitted title to sea country will be decided in one proceeding with full evidence, rather than in piecemeal determinations that might lack critical context.
The ruling also signals the court’s impatience with slow progress in related proceedings: the TSRSC Part B and three Kaurareg claims have been in mediation for years with unresolved tenure issues. By threatening consolidation unless settlement is reached by October 2026, the court applied pressure to conclude long-running negotiations and move toward final determination of competing claims across the region.
