One of Queensland's most senior police officers has refused to shake the hand of a Gold Coast police whistleblower accused of leaking security vision of an alleged assault by colleagues.

Sergeant Rick Flori appeared in a compulsory dispute resolution conference in the Queensland Civil and Administrative Tribunal (QCAT) with a Deputy Commissioner, two assistant commissioners and the head of a major taskforce.

A non-publication order means parties cannot reveal what was discussed, but it is believed the matter was unrelated to the Sergeant's criminal prosecution for whistleblowing.

The group met for nearly one and a half hours.

Before mediation began, Assistant Commissioner Steve Hollands refused to shake Sergeant Flori's hand.

Sergeant Flori said it was appalling.

"That's a sign of the mentality of some people I guess. I was happy to meet all of them," he said.

Sergeant Flori has been stood down on full pay, charged with misconduct in a public office, and risks losing his job after nearly 25 years' service.

He is accused of leaking footage of an alleged police assault in 2012.

The leaked surveillance footage allegedly shows four officers bashing a 21-year-old man in handcuffs at Surfers Paradise police station.
