Statoil makes huge margins on their oil because once the tricky rig was set up, it just comes out like Gold.
Most other natural resources have much thinner margins due to processing, overhead.
'Sweet Crude' i.e. the kind you get in the desert, and 'sweet once it's setup to be' i.e. Statoil ... this is a different thing together from other natural resources.
Norway is like Kuwait, it's almost impossible to compare it to anything else.
They can leave the Oil in the ground for now because they are very rich and have more money than they know what to do with.
As far as I'm aware, profit margins on iron aren't too shabby either, though I'd have to do some digging how this all shapes up in these specific cases (Norwegian oil vs Australian gold, iron and coal).
Australia's top exports are also based on natural resources, namely, Iron Ore, Coal Briquettes, Gold and Petroleum Gas, accounting for 60% of all exports at $144.6B. Assuming a population of 24.6M, this translates to $5.9k per person.
Point is, while Australia isn't quite as well off as Norway, there are resources aplenty to pull off something similar on a somewhat smaller scale.
Metals is an interesting case because on the one hand they are definitely a non-renewable resource. On the other hand, it seems like there's a difference between exporting ore and exporting refined metals, in terms of whether it's "just" resource extraction or not...
Iron ore extraction isn't bad but it's nowhere near as profitable as Norway's oil extraction
You'd have to do that across the entire range of resources and then divide per capita - on that basis I think Norway would blow by 4x Australia just based on off-the-top of my head estimate
You should not look at just oil, but natural resources in general (in case of Australia, iron, coal and gold in particular).
Norway still comes out on top, but only by a factor of ~2 (cf https://atlas.media.mit.edu/en/profile/country/nor/ https://atlas.media.mit.edu/en/profile/country/aus/ ).
