About this data
These statistics summarise decided development applications recorded against Mundoolun properties in Logan council records, current as of 8 July 2026. Past decisions describe how comparable proposals have fared — they do not guarantee, and cannot predict, the outcome of any future application. Council assesses every application on its merits against the planning scheme that applies at the time. This page is general information, not planning or legal advice: what is achievable on a specific site depends on its zoning, overlays, lot dimensions and assessment pathway.
