A Franklin man has pleaded guilty to importing more than half-a-kilogram of illicit drugs to Canberra post office boxes under false names.
But Yavuz pleaded guilty on Thursday to 23 counts of importing cocaine, MDMA (methylone), and amphetamines between September 2013 and January 2014.
The court heard on Thursday the prosecution and defence were yet to negotiate an agreed statement of facts.
Justice John Burns also heard the amount of drugs imported – estimated to be up to 618 grams in total – would also need to be confirmed.
Yavuz was arrested in December 2013 and charged with drug offences after Customs detected a package at a Sydney mail room.
Authorities replaced the drugs with an inert substance, and allowed Yavuz to pick it up. Police then raided Yavuz's Franklin home, where they allegedly found a list of tracking numbers, fake licences, and keys to post office boxes across the capital.
The prosecution sought to revoke Yavuz's bail during the brief appearance before Justice Burns.
The prosecutor argued Yavuz posed a flight risk as his inevitable jail sentence approached and he could obtain fake identification.
Defence lawyer Kamy Saeedi conceded a jail sentence would be likely, but said his client had been compliant while on bail.
Justice Burns acknowledged Yavuz's conduct while on bail had been impeccable, but said the urge to do something foolish became greater as the sentence date approached.
The judge remanded Yavuz in custody and ordered a pre-sentence report be prepared for a June sentence hearing.
