I can confirm a raid (six agents plus dogs) for as small as 5g of 4-MMC, dollar value well under $100 AUD at the time.
Cases were also dealt with in Magistrates Courts but under Federal law, be aware that because of evidence collected such as receipts/CC records whether digital or otherwise, these can be used as evidence for a charge of "attempted importation". They do not need to have seized the physical contraband, for example if they have one package and proof of other orders either placed or received, such charges can be laid at the discretion of the CDPP.
In one case, a defendant was charged with and plead guilty to a federal charge of "possession of LSD" even though the seizure took place in a mephedrone raid in Victoria, lawyers inform that this charge is rare and is normally handled under state law. Federal charges of possession normally apply only to the NT and ACT.
Thanks for this, if you have any others related to the 2010 Federal mephedrone raids I'd be interested to read it.
