I admit I've been too lazy to publish the stuff I'd already done with 
the GA dataset. Rather than making people do it all again I've finally 
got round to putting it on GitHub https://github.com/FrakGart/ga_streams

I have already imported in the named streams in NSW except for the area 
around Sydney. Mostly, again, due to laziness. As already pointed out 
the data all needs to be sanity checked against what's on the ground and 
that's really hard when it's under a city.

The data is organised by AWRC catchment, so for Sydney you are looking at:

https://github.com/FrakGart/ga_streams/blob/main/Basin_II/II12.osm.gz

which is the Hawkesbury River and

https://github.com/FrakGart/ga_streams/blob/main/Basin_II/II13.osm.gz

which is Sydney Coast-Georges River

You can use overpass turbo to see what is already mapped:
