If the manufacturer can’t prove that the aircraft comply with the ASTM requirements, they will be grounded and unable to be used for hire or reward. In theory they can be registered under LSA experimental but you’d have to think that CASA would not allow this if they believe that the aircraft type is unsafe.
I hope nobody has bought any of those used ones as that may raise a few concerns.
