According to the QLD topo maps the junction between Hope and Ravensbourne is here OpenStreetMap. This matches what’s on the 1920 4 inch to a mile map https://apps.information.qld.gov.au/data/v2/HistoricalMaps/StaticMap/cadastral/cad-map-4mile-queensland-1st-series-sh7c-1920/original. However, by 1956 Hope Creek is shown as continuing down the west and joining after the road crossing https://apps.information.qld.gov.au/data/v2/HistoricalMaps/StaticMap/cadastral/cad-map-2mile-qld-2m176-1956/original.
So at some point someone decided that Hope Creek crossed the road and then later it’s been switched back.
By the way…all of the streams in this area seem to be currently flowing uphill.
