A woman who had more than $200,000 of suspected drug money stashed around her bedroom has been given a fine and a good behaviour bond in a Sydney court.

Katiusha Stepanyan, 28, pleaded guilty in February to one charge of dealing with proceeds of crime after police discovered the cash when they raided her North Ryde home in March 2017.

Detectives had gone to the home on the morning of March 8 to serve a firearm prohibition order on her older brother Dimitri. They obtained a search warrant after finding "a number of items of interest" unrelated to him.

During the search of the four-bedroom home, police found a mixture of $50 and $100 notes totalling $220,500 in Stepanyan's room.
