Registered here vs used here
The RIR count is what was allocated to organisations registered in Australia; DB-IP’s count is where it estimates addresses are used. DB-IP places 10,972,453 more IPv4 addresses in Australia than were allocated here, which happens when networks registered elsewhere (cloud providers, multinationals) operate in the country.
