How we keep figures current
Each tool shows the date it was last reviewed. Costs are ranges compiled from published Australian cost guides, and rules and rebates are checked against government and regulator pages. Where we use our own simple adjustments, such as city multipliers, the page says so. Prices, rebates and permit rules change, so check the source before you sign anything.
