The AURIN data discovery and portal sites are a good place to start.  I don't know if it applies to your case, but any researcher in an Australian university or government agency has access through the Australian Access Federation system.
https://aurin.org.au/

The Public Sector Mapping Agency provides a number of data sets. 
https://www.psma.com.au/

In addition to the SDI interface you list, NSW has the SIX interface.  It likely has similar content to the SDI but I have not checked.
https://six.nsw.gov.au/

There is also http://data.gov.au .  A subset of the data is spatial, but much of it might already be available through the National Map.

Regards,
Shawn.

Hi all,


I have a professor (landscape architecture) looking for sources of GIS data for Sydney and Melbourne. I've provided her with a few starting points, but am hoping some of you might have a few additional resource recommendations. The following resources are what I have suggested so far:

University of Melbourne Library GIS data resources guide:
http://unimelb.libguides.com/GIS

Australia National Map:
http://www.nationalmap.gov.au/

New South Wales Spatial Data Catalogue:
https://sdi.nsw.gov.au/nswsdi/catalog/main/home.page

Victoria Open Data Directory:
https://www.data.vic.gov.au/data/group/spatial-data

Thanks!
Matt
