How we price this for Gold Coast
We take each Australia national base range and multiply it by a local index of 0.95, built from SA4 employee-income data (ABS Personal Income 2022-23) (there is no Australia equivalent of the U.S. Regional Price Parity, so the price and overhead terms are held at the national baseline):
index = 0.95
The wage term uses Gold Coast vs Australia. Parts ship at national prices, so only the labour share moves with the SA4 region. All figures are in Australian dollars — we never convert prices from other countries; the Australia base ranges come from Australian sources. Full weights and vintages are on the methodology page.
