Looks like 254,700oz are hedged from FY21 production guidance of +600,000oz so i wouldn't say gold price rises don't mean alot. Hedging decreases in FY22 to 190500oz and then 48000oz in FY23.
From the quarterly -
At 30 June 2020, the hedge book comprised 493,200oz at an average delivery price of A$2,094/oz.
