Even though i've gone down before with intercepted seeds, i don't find this news too disturbing.
Firstly, Agriculture Department (not so concerning) will be monitoring what the Biosecurity Department (quite concerning) find.
Secondly, they'll most likely only bother scanning mail from those countries they mentioned ("China, Malaysia, Taiwan and Pakistan predominantly").
And last but not least, due Covid, you will see a shopping trend around the world that will see people buy more shit online, than walk-in retail stores, which in turn loads up the postal/delivery systems within the country, and make individual package scanning even harder.
Just refrain from bulk orders, and using real name and grow address.
