Danielle White, 45, made the comment yesterday and said her younger son's 16th birthday would now be ruined after having an application in the Warrnambool Magistrates Court to change her bail conditions denied.

Ms White allegedly took over a drug trafficking operation run by her 22-year-old son Benjamin White, while he was in prison. She was released from custody on June 6 with a $20,000 surety.

Ms White was one of 17 people police arrested early this month as part of Operation Caspa.

Magistrate Jonathan Klestadt yesterday refused the application after hearing that Benjamin White was expected to be interviewed and charged by police over his alleged part in a drug ring.

He said it was inappropriate for Ms White and her son to be in contact until police had laid charges.

Mr Klestadt said the Whites could act together to defeat charges which could be laid against Benjamin.

The court heard that Ms White was now living in Koroit while her son would be living in Warrnambool when released.

He was sentenced to serve three months in jail during March after pleading guilty to recklessly causing injury, making a threat to kill and causing criminal damage as well as breaching a suspended jail sentence and a community-based order.

During Ms White's original bail hearing on June 5, Senior Constable Wayne Ryan, of Warrnambool police regional tasking unit, told the court that alleged co-offender Dianne Ellis, of Narrawong, supplied Ms White with cannabis and amphetamines.

Police said they would use about 1000 telephone intercepts in their case against Ms White.

It was alleged Ms White had been arrested trying to smuggle cannabis into Fulham Prison where her son is being held.

However, Ms White's defence counsel Raj Bhattacharya told the court that the cannabis was found in Ms White's car outside the prison and that it was for her personal use.

Ms White was brought to tears at the end of that hearing when she was ordered not to have contact with her son Benjamin.
