Hi Mike, looking at a project that has a custom Projection that isn't yet defined in GM or in the supported EPSG.
I've tried setting up a Datum but I'll be honest, I don't know what I'm doing.

I'm trying to get it to align with other data which is at MGA Zone 55 GDA94

This site has all the info for the projection
The ACT Standard Grid - Environment and Planning Directorate - Planning

And here's a custom datum I tried to setup, but it doesn't seem to work

Can you see what I might be doing wrong here

Many thanks, Matt
