I think it's better interpreted as comparing effective tax rates, i.e. 27.6% vs 31.9% of gross income. You're right that the salaries not directly comparable for the reasons you listed, but it's also pretty clear that they're not that far apart. Certainly not enough to conclude that Australians are "paying higher taxes to offset the cost of health care". By examining the numbers it's pretty clear that we're paying more for health care in the US and getting less for it.
