Former Australian swimmer Geoff Huegill and his publicist wife Sara Hill have been allegedly caught with cocaine at Sydney's Randwick racecourse.

Accused: Geoff Huegill and wife Sara.

Accused: Geoff Huegill and wife Sara.

Police were allegedly patrolling the venue on Saturday as part of their regular duties when they were called to a suite in the grandstand by a security guard.

About 5.40pm, police spoke to Huegill and Hill who were allegedly in possession of a small quantity of white powder which police will allege was cocaine.

One racegoer told the Herald that up to 30 police officers swarmed into a number of private suites and stopped people as they were coming out of the bathrooms.

"They were everywhere, outside every door," he said.

A racegoer said both uniformed and undercover police were concentrating their search on an exclusive members area called The Stables.

"It was some time in the afternoon with police in uniform and undercover and with several dogs."

One employee said Huegill was one of the first people police spoke to and said he initially refused to be searched.

She said she later saw Huegill and Hill being escorted from the races.

The employee said up to seven police officers were seen talking to Huegill.

"They pulled him out of the suite and asked him why he was about to leave.

"He looked nervous and refused to be searched and kept asking for a lawyer," she said.

She said Huegill was taken from the suite to a private event area for further questioning.

Huegill and Hill were charged with possessing a prohibited drug and will appear in Waverley Local Court on May 14.
