Undercover police have told a Brisbane court of the day the man accused of murdering Daniel Morcombe led them to the crime scene in 2011.

Undercover officer "Fitzy", who posed as a crime boss, today continued his testimony at the Supreme Court trial of Daniel's accused killer, Brett Peter Cowan.

Cowan, 44, has pleaded not guilty to the boy's murder in 2003 on the Sunshine Coast, and the defence has previously said the confession was false.

The trial has been hearing secret tapes of Cowan's conversations with the officers.

At one point, he describes the way he strangled his victim.

Cowan took two officers to a bus stop and is heard describing how he offered Daniel Morcombe a lift to an abandoned house.

Cowan told the officers he wanted to "have fun" with the boy and tried to pull his pants down.

He said Daniel responded by saying "oh no" and when Cowan thought he was going to run, he choked him and felt something snap in his neck.

He also showed the officers a creek where he said he dumped Daniel's clothes.

Last week, the jury heard Cowan's taped confession to a fake crime boss in Perth in 2011.

In the recording played to the court today, Fitzy, who accompanied Cowan to Queensland under the ruse of helping to cover up the crime, told the accused killer: "This time next week it will all be in your past".

The officer told the court that he, Cowan and another undercover officer called Ian, flew to Brisbane in 2011 then drove to Beerwah on the Sunshine Coast.

In the tape, Cowan said he offered the teenager a lift to a shopping plaza from a Sunshine Coast bus stop.

He said he told the boy he had to "duck home" first - and took him to an abandoned house.

Fitzy told the court that Cowan had showed him to a macadamia farm at Beerwah and described how he lured Daniel inside a building with an offer of a glass of water.

The officer says Cowan described how he killed Daniel in the demountable building, carried the boy's body out, and put him in the back of his Pajero four-wheel drive.

He said the accused and the officers then drove to a creek where Cowan said he had thrown Daniel's clothes out of the car.

On the recording, Cowan said he would take the battery out of his phone in case police had his number and "they can suss out through towers".

Fitzy says Cowan also directed them to his former home, his drug dealer's home and Nambour Connection Road.

Last week, the court was played a video of a meeting between Cowan and an undercover police officer posing as a crime boss at the Perth Hyatt.

Cowan confided the death of Daniel was his "deepest, darkest secret" that he had not told anyone.

On the video, Cowan said he offered the teenager a lift to a shopping centre but instead took him to a house near an old sand mine at Beerwah.

Cowan said Daniel panicked and he then choked the teenager.

The trial is continuing.
