I expect the source you are using is…
https://spatial-img.information.qld.gov.au/arcgis/rest/services/Basemaps/LatestStateProgram_AllUsers/ImageServer
Under the service description it states
“Aerial imagery that is three years or older captured under SISP is made available for public use openly by the Department of Natural Resources, Mines and Energy, Queensland.”
Further down the page the source copyright is listed.
I expect osm needs to obtain explicit permission to use this source as we are not able to satisfy the copyright requirements in the normal way.
