If you divide 100 by the 6 states and NT (ignoring the ACT) you get 14. So the percentage of GSP of the Australian economy is exactly average.
You've chosen to look at the resident population to say it's above average GSP per capita. What about GSP per sq km? Then it's below average as it should be 33% as it occupies 1/3 of the area of the country?
