My main area of interest from a stream point of view is the Hawkesbury
Catchment, outside the Sydney suburban boundaries.
I haven't been involved in any imports so you'll have to excuse my
ignorance.
Could the dataset be split into say urban/non-urban and the non-urban
parts imported? Or do partial imports just create more work? What sort
of sanity checks need to be carried out?
cheers
Tom

I should add that I have only used the Surface Hydrology Lines from

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:
