Summary of effective income tax rate
1.
Subsequent to achieving first oil on the Sangomar project in June 2024, the Group has recognised a net deferred tax asset of $305 
million. The remaining $61 million relates to other tax benefits previously unrecognised. The expected sale of Woodside’s
15.1%
share in the Scarborough Joint Venture resulted in the recognition of a net tax benefit of
$91 
million. These events have resulted in a reduction of the global effective income tax rate from
25.6% to 6.9%. In the prior period, as a result of the final investment decision to develop the Trion resource, the Group recognised deferred tax assets of $319 million, resulting in a reduction of the global effective income tax rate from 29.6% to 13.9%.
