No, absolutely not. Australia is NOT part of the EU, UK, or US domestic plans. Most home carriers (like AT&T, Verizon, T-Mobile, or UK's Vodafone/O2) will charge you expensive international "Day Pass" rates (e.g., $10-$15 per day or £6 per day). A Cellesim eSIM is a one-time prepaid fee that is significantly cheaper.
