Two people have appeared before the Darwin Magistrates Court on drugs and corruption charges following a police sting last week.
On Friday six people were arrested as part of an ongoing police investigation into drug offences, official corruption and unlawful disclosure of confidential information.
Those arrested included prison officers, a police officer and a firefighter.
Prison officer Sarah Rudd, 24, is facing 25 charges including corruption, illegally obtaining confidential information and the disclosure of official secrets.
She has also been charged with drug offences and communicating with a prisoner without permission.
Rudd's lawyer Peter Maley told the court she wanted restrictive jail conditions imposed on her to be removed because she did not think she needed protection in jail and wanted to be treated like any other prisoner.
She is expected to apply for bail on Friday.
A second accused, Phillip Kaye, also briefly faced court on eight charges including corruption and drug possession.
He will be back in court for a bail application on Tuesday.
