The daughter of Collie-Preston MLA Mick Murray faced the Bunbury Magistrates Court on Wednesday charged with drug offences after a police raid.
Police executed a misuse of drugs act search warrant on the East Bunbury home of Bree Murray, 35, on Tuesday.
It is alleged they found approximately 101 grams of methylamphetamine, 125 grams of MDMA, 20 grams of cannabis and $1,700 in cash during the search.
Police inquiries are continuing and a male resident of the address is still to be spoken to by police.
Ms Murray has been charged with two counts of possessing a prohibited drug with intent to sell and supply and one count of unlawful possession.
Mr Murray said in a statement that his daughter had an ongoing battle with drugs.
"My daughter has been fighting a 15-year addiction and we will continue to stand by her to give her the love and support she needs," he said.
"Like many other families, we have been touched by the terrible scourge of drugs.
"My wife Anna and I and my other daughters are uniting and regrouping to do all we can to help.
"We appreciate privacy on this matter at this very difficult time."
The street value of the drugs was $150,000.
