Background 

In December 2020, the Gudanji, Yanyua and Yanyuwa-Marra peoples filed a compensation claim for economic loss and cultural loss caused to them by the McArthur River mine project – a zinc and lead mine first opened in the early 1990s. The claim was brought under the Northern Territory legislation that permitted the mine, but the Court’s assessment of compensation was made using the principles of the Native Title Act 1993 (Cth) (NTA). The claim group was represented by the Northern Land Council. 

Summary of the Judgment 

On 27 February 2026, the Federal Court delivered judgment awarding over $55 million in total compensation. This comprised $743,408 for economic loss plus interest, and $54 million for cultural loss, with the latter reduced from an assessed $60 million to reflect benefits received under a December 2025 Indigenous Land Use Agreement (the 2025 ILUA) with Glencore, the mine operator. The decision is the largest native title compensation award in Australia and illustrates how the principles established in the Timber Creek case are applied to mining projects. 

Economic Loss Assessment 

In assessing economic loss, the Court rejected the applicants’ proposed “hypothetical bargain” approach, which would have estimated the payment that might have been agreed between the parties at the time of the relevant acts. Justice Banks-Smith considered that approach inconsistent with the Timber Creek framework, which requires compensation to be assessed by reference to land value rather than would-be commercial negotiations.  

Instead, the Court followed the methodology adopted in the Timber Creek decision: identifying the compensable government acts that enabled the mine development, determining the freehold value of the affected land at the time of those acts through expert valuation evidence, applying a percentage to reflect the proportionate value of native title rights compared with freehold title, and aggregating those values across the affected areas.  

Applying this framework resulted in a modest economic loss figure of $743,408 when compared against the economic value to the mining operator and the Northern Territory government which has generated significant wealth over the decades of its operation. The decision reinforces that courts are likely to continue applying the Timber Creek land valuation model rather than royalty-based approaches, meaning that economic compensation will remain relatively limited, particularly in remote areas where land values are low.  

It is noteworthy that the Court did say that the hypothetical bargain may apply in other cases with different facts and forms of evidence.  

Cultural Loss 

The cultural loss award of $54 million was assessed by applying the principles set out in the High Court decision in Griffiths and relied heavily on evidence given by Traditional Owners and anthropological evidence to demonstrate the interconnected nature of sites, stories and cultural practices across the affected landscape. 

 Justice Banks-Smith accepted evidence that the impacts extended well beyond the destruction of particular sites and affected the broader integrity of the cultural landscape and the relationship between Traditional Owners and country. This included harm to cultural responsibilities, disruption to spiritual connections, and impacts on the transmission of knowledge across generations. The judgment recognised that the impacts of the project extended beyond the immediate physical footprint of the mine and port. Further, the diversion of several kilometres of the river and development of the mine were found to have caused irreversible disturbance of Dreaming sites and tracks. From this evidence, the Court found that the claim group experienced diminution of their traditional connection to Country, including their ability to care for and receive from Country, and described the harm as intergenerational and enduring.  

The final award for cultural loss was reduced by 10 per cent to account for benefits provided to the Traditional Owners under the 2025 ILUA.  

Role of the ILUA 

The respondents argued that the benefits to Traditional Owners under the 2025 ILUA should result in cultural loss being reduced by 50% on the basis that the drafting demonstrated consent to the project for past and future acts, and that it was an answer to many aspects of cultural loss argued by the applicants such that any cultural loss award should be reduced to prevent “double dipping”.  

Ultimately, the Court concluded that the 2025 ILUA will ameliorate some of the concern and uncertainty experienced by the Claim Group and mitigate further loss of country including enhancing capacity of the Claim Group to speak for country going forward on cultural heritage matters and scared sites. Whilst the financial terms of the agreement did not affect the compensation sum awarded to the Traditional Owners by the court, the existence of particular terms regarding mining rehabilitation, cultural heritage managements and the like was taken by the Court to mitigate future cultural loss and therefore the Court reduced the overall sum of cultural loss compensation by 10%. 

What does this decision mean? 

In light of the McArthur River Mine claim, native title holders should pay attention to the following:  

• It is unclear how (or whether at all) native title holders are entitled to economic loss calculated by reference to what the land was used for (ie. native title holders may not get more compensation for a mine than for other less profitable uses of the land);  
• Compensation for cultural loss will be assessed holistically and based on the evidence given by native title holders about the impact on their relationships between one another and with Country; and  
• Benefits received by native title holders under an ILUA may result in a discount in compensation for cultural loss and careful wording and appropriate advice should be sought on any such agreements.
