I read your comment, but in the absense of any specific examples it was hard to know the details of the problem. The OSM Wiki contains a Data Catalogue for Australia. https://wiki.openstreetmap.org/wiki/Australian_Data_Catalogue https://wiki.openstreetmap.org/wiki/Australian_Data_Catalogu... The issue right now is that both the PSMA data (that you want OSM to use) and the ASGS data (that you infer it is using - and in some cases that might be the source of the boundaries that were entered, but it is not officially in use by OSM) are licensed under CC-BY, which is not 100% compatible with the ODbL that OSM uses. The necessary solution is to request an explicit waiver from the data provider, which has been requested for PSMA, but (as far as I know) never received a response.
