I think you're correct. The post is 5 years old and data users and mappers (people editing the map) still use it the same: assume WGS84, be aware that sometimes in some regions that might not be 100% accurate. Those needing centimeter accuracy will use government data, for Australia that would be GDA2020 (which replaced GDA94). Car navigation (assuming a human driver) hardly needs meter accuracy. https://www.icsm.gov.au/gda2020 https://www.icsm.gov.au/gda2020
