Nah. Nothing
she's talked about is remotely comparable to the Australian situation.
Her most severe proposals are reinstating the "assault weapons ban" and repealing the "Protection of Lawful Commerce in Arms Act". Fat chance, and neither of those relate to the Australian situation.
To emulate Australia, She'd have to nationalise firearms laws, institute federal licencing, permits to acquire and registration, revoke self defence as a legally recognised reason for firearms ownership, restrict access to semi-auto centrefire rifles to professional hunters, restrict handguns to club competitors (and ban compact and subcompact models), restrict pump action shotguns and rim fire semi-autos to farmers and then have the mother of all buyback schemes.
All this after failing to even manage a bill for universal background checks.
Not happening.
