On 10 August 2020, the surrender of WA-430-P was approved for operator Woodside Energy Ltd. In its place, Woodside was awarded two retention leases in April 2020 over the Toro (WA-93-R) and Ragnar (WA-94-R) gas discoveries. WA-430-P had been valid for around 11 years before effectively being relinquished on 29 April 2020.  Upon its award, WA-430-P covered an area of 560 sq km. In a second area change in 2017, Woodside relinquished around 65% of the area, to exclude the dry Gumbo 1 exploration well, which was drilled in 2013. The remaining area upon relinquishment spanned two blocks of 80 sq km each, covering the Toro and Ragnar discoveries. The newly replacement retention leases are valid until 2025.  Woodside received approval to relinquish exploration permit WA-430-P on 10 August 2020, effective from 29 April 2020. Participants in the permit were Woodside Energy Ltd (70% + operator) and Mitsui E&P Australia Ltd (30%). This ownership is also reflected in retention leases WA-93-R and WA-94-R.
