Brynne Edelsten was arrested and charged earlier this month with possession and trafficking of the drug ice following a raid on a property in which she had been visiting, at Hazelwood Road, Boronia, in Melbourne.
The 38-year-old, who is set to appear on season 2 of SAS Australia, has promised to "vigorously fight" the charges.
Brynne was initially let go, but was arrested and charged a day later.
A 39-year-old man was also charged for trafficking meth and alprazolam, which is also known as Xanax.
In a statement to Yahoo Lifestyle, Brynne has described the charges as "shocking" and vows to fight them.
"Earlier this month, I was charged with criminal charges," she said. "I am shocked and saddened by these events and will be vigorously fighting all charges.
"I am very thankful for the support of the team around me and will not be making any further comment."
Victoria Police said in a statement to Yahoo Lifestyle, "Police from Knox uniform executed a warrant at an address in Boronia as part of an ongoing drug investigation on Tuesday, 11 May.
"Officers attended the Hazelwood Road property about 3pm and seized what is believed to be magic mushrooms, methylamphetamine, prescription drugs and an allegedly stolen electric bike."
They added, "A 38-year-old South Melbourne woman was spoken to at the property and released without charge. After further enquires were made the woman was arrested and charged with traffick methyl-amphetamine, possess methyl-amphetamine, use methyl-amphetamine and deal property suspected proceeds of crime.
"She was bailed to appear before Ringwood Magistrates’ Court on 8 October. The arrests form part of Operation Wipeout, an ongoing operation targeting drug trafficking in the Knox Police Service Area."
The other man involved will face court on August 3.
Brynne was famously married to millionaire Geoffrey Edelsten for four years, before separating in 2014.
She is also set to appear in the new series of SAS Australia, which began filming in the Blue Mountains last month.
