The issue for me is that when I do a search for 3 Remington Drive, Highett, OpenStreetMap says it is in the City of Kingston (true), postcode 3192 (incorrect, Remington Drive is in Highett VIC 3190, OSM is giving the wrong postcode. HIGHETT is in postcde 3190, that's my issue, not a big deal but still returning the wrong postcode in a search result.
