They only just changed the laws a month ago to make it so opaque and vague about who qualifies as a tax-resident or not. It's basically a "if we want we will tax you" situation. The 183 day rule means little if you have even something as innocuous as a bank account back home now. It's a ridiculously stricter change that is entirely open to interpretation by the ATO.
Sounds like they're just 'recommended' for now but won't take effect till next tax year at least.
Also sounds like its intended to catch people working 0% tax contracts in the middle east or digital nomading around east-asia till they need medical care. (still not a good reason to complicate things)
What you are describing is a pretty common requirement. Canada has a similar requirement, and while a passive bank account would in itself not be considered 'ties' to the country, an active one that sees use might.
