How we price this for Newcastle
We take each Australia national base range and multiply it by a local index of 1.01, 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 = 1.01
The wage term uses Newcastle and Lake Macquarie 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.
