Ultimately the States have no jurisdiction when it comes to enforcing public health measures relating to: quarantine, forced vax or forced, coerced or other means of performing PCR-Tests. These are merely directives dressed up as ‘law’.
Only the federal government has the power to do this, under VERY STRICT conditions through the Biosecurity Act 2015 (Sect 60 & 61) – this involves a ‘biosecurity control order’ being issued by a judge in court and delegated through a human biosecurity officer. Again, VERY STRICT conditions apply to this order!!!
The States like playing the proverbial ‘ducks and drakes’ claiming that the Federal powers have no effect when it comes to the State – but ultimately they are VERY wrong. Again the classic Commonwealth Sect 109 – Inconsistency of laws also comes into play here.
