There's a lot of detailed in this (though it is old):

If the recovery rate can be increased (see previous posts, has been strongly hinted at by PMG), it could be a serious gamechanger over and above current valuations:
Back in 2018 PMG undertook a study through AGR to model potential fracture stimulation of the reservoirs, which concluded (at least to the extent that has been announced publicly to date) - "New GPA reservoir study concluded that stimulating the Claymore formation WOULD result in a considerable increase in well productivity and is likely to increase the project’s oil recovery factor."
A few years earlier, Senergy estimated 24% recovery rate for Perth, when 2P was given as 41.3MMBbls. In a research note, Charles Stanley had to say about it: "For Phase 1, our economic valuation assumes a recovery rate of 24% (based on the Senergy 2P estimates). We expect the actual recovery rate to vary from this current best estimate, perhaps materially because there is quite a bit of uncertainty, in our opinion, relating to the distribution of higher quality sands within the heterogeneous Claymore reservoir. Recovery estimates for the Claymore and Scapa fields, which also produce from Claymore sands, increased over time to 40% and 56% respectively (according to the operator Talisman Energy's most recent publicly available estimates)."
The 2P figure hasn't changed to date, but if there is any validity to the carry across from Claymore and Scapa, then the recovery rate could potentially be doubled - which would be nice..
