I wouldn't hold my breath. Google's adoption of updated information for anything other than the capital cities is extremely slow. On the order of the data has been in OSM for five years slow.
Google has photographs of my house from above, and from the road, and doesn't list the road as existing.
They're probably inclined to add this GPS shift data for the capital cities - but the mapping data will probably be inconsistently updated.
Especially as the state and territories provide the data in an incredibly wide range of formats.
VIC, NSW, SA provide shapefiles, which is great, as it is becoming one of the more popular standard. (They also export for a range of other data types).
The NT provides a strange mix of shapefiles and custom xlsx sheets. Unless you're looking at Darwin or the heart of the Kimberly's, you'll be looking at human-written Excel sheets for a lot of this.
QLD, the ACT and WA seem to use OpenGIS/ArcGIS XML files.
Tasmania doesn't maintain their own data, but relies on ANZLIC to do it for them, and seem to be in the middle of an argument over who will do the maintenance moving forward. (The last update to any of their public data appears to be in 2016.) This was shapefile/export like VIC, NSW and SA, but it becomes somewhat useless if it never gets updated.
If you're an islander, you sort of have to hope that the state/territory includes you in their dataset. They don't always. And they're not consistent about when they include you. Regressions are common. Councils tend to maintain their own data, but rarely allow anyone access, paid or not. If you hand them a FOIA request to see the data, then... Well, I got handed a series of printed XML documents, after six months of them threatening to take me to court for requesting it. Multiple island "councils" (often different names, but similar functions) did this.
