Lake Illawarra police charged a 22-year-old woman with multiple drug offences on Thursday.
In January this year, police from Lake Illawarra Local Area Command formed Strike Force Walder to investigate the sale and supply of prohibited drugs in Figtree.
At the end of April, investigators executed a search warrant at an Albion Park Rail, home.
During the search officers allegedly seized more than 100 MDMA tablets, cannabis, ketamine, lysergic acid, drug equipment, mobile phones and cash.
The woman was given conditional bail.
