Asset recovery action was taken in relation to approximately $10,000 in cash and the property itself.
The assets were restrained under the Criminal Proceeds (Recovery) Act 2009 and the High Court determined in a civil forfeiture order that Rissman had unlawfully benefited by $200,000 from the significant criminal activity.
Detective Jayne Bretherton said illicit drug use accounted "for millions of dollars of social harm every year".
"Police will continue to target criminals and ensure they do not profit through their offending to illegally accumulate assets and wealth," she said in a statement.
Anyone who has concerns about illicit drugs or proceeds obtained from crime is asked to get in touch with police.
