^ You absolutely right, articles are regularly published in forensics journals containing information on the content and quanatity of chemicals and adulterants in pills. There isn't a wealth of information from Australia, but it's just wrong to believe that Australian pills are going to be different from pills world-wide.
The one paper of this nature in Australia reports no pills containing opiates. Out of 84 relatively randomly collected pills submited to an authorative GCMS, 49 pills (58%) were MDMA only, and 31% contained no MDMA whatsover. None contained opiates.
It's worth noting that this sample contained the pills reported by users to be "tripstacy" the LSD containg pills. "Surprisingly", the pills did not contain any lysergide of any kind.
Of the 1000s of pills seized by the South Australian Police, 89% were MDMA containing, and and again no opiates
