you may also be interested to look at the LOC-I project ( location Index project).
It has a selection of tools ( though some not fully complete) to obtain linked data sets of GNAF adresses, ASGS and geofabric objects.
If supports asking things like ( as stated on the loc-i info)
- Which StatisiticalAreaLevel2 feature is this Address point within?
- How many addresses are within this StatisticalAreaLevel4?
- How many Meshblocks are within this catchment?
- How many addresses are there in the overlapping intersectional area between this Meshblock and this Catchment?
Unfortunately the full implementation does not yet support a live data endpoint (sparql or rest) and the example GNAF data download only covers the ACT. But with some python and setup of local linked data servers ( using free tools e.g. GraphDB) all data can be queried on your local machine.
Of note is that the data joins address, mesh blocks and gives a method of handling addresses in a standardised manner using a comprehensive schema (vocabulary).
To get a taster you can search for individual addresses, localities or mesh blocks and explore the links using the below tools and download sub sets of data easily.

Use this vocabulary to improve the expressiveness and control of address feature data in your project http://gnafld.net/def/gnaf
All the best
