Yeah, my state's Department of Transportation runs a GBAS/CORS network and anyone can have access to it just by asking. Trouble is, that (and Galileo HAS) assumes you have internet access. Maybe you're so far out in the middle of nowhere (This is Australia we're talking about in TFA) that the internet isn't available, or reliable. So maybe you think satellite-based corrections are the way to go, but I concur, a local RTK reference would also work. (But 99.9% of the time, the satellite service is gonna be less hassle.)
