Daniel Morcombe.

Deputy Police Commissioner Chris Dawson today publicly acknowledged the valuable role played by WA Police in the Daniel Morcombe murder investigation, which led to Brett Peter Cowan's conviction today.

"I think it is important to publicly acknowledge that there were dozens of West Australian police who worked tirelessly under very stressful conditions for many, many months," he said.

"Their contribution to this, in support of our partners in Queensland police, was very important in the investigation outcome that we've seen today.

"It was a very difficult investigation, which Queensland police had with great support from WA Police.

"It's a good example of both jurisdictions working co-operatively together."

Mr Dawson would not comment on whether police had any concerns about the amount of information regarding undercover police tactics which were made public during the murder trial.

"I wish to acknowledge that it was a very skilful operation but I'm not going to comment or elaborate on the nature of what they did," he said.

Mr Dawson said he believed the investigation and successful conviction of Cowan was an example of the relentless efforts of police in investigating crimes.

"It is a very good example of in the pursuit of justice, that police officers working with partner agencies, will not give up and we will work as hard as we can to support the loved ones in their grief and, importantly, to bring people to justice," he said.

Mr Dawson said WA Police were proud of the officers who worked tirelessly on the investigation.

"We're obviously very pleased that WA Police were able to make a contribution to this nationally important investigation to support the Queensland police and as it went through the court process," he said.
