DJs Mel Greig and Michael Christian, the 2day FM DJs implicated in the suicide of a London nurse, are unlikely to face charges for their royal prank call.
London police have since made no contact with local Australian police despite threatening criminal charges against the pair.
New South Wales deputy commissioner Nick Kaldas confirmed that there has since been "no contact with the London Met" and that contact between the forces was made three weeks ago just to "touch base".
Kaldas added: "We're happy to assist but they're not asking for anything and we don't anticipate they're going to be asking for anything."
Greig and Christian have been off air since Jacintha Saldanha committed suicide on Friday 7 December, a matter of days after she answered the prank call from the DJs.
The DJs then spoke to a nurse caring for the Duchess of Cambridge - who at the time was a patient at the King Edward VII's Hospital suffering from acute morning sickness - pretending to be the Queen and Prince Charles.
In one of the three suicide notes left by Saldanha she blamed the radio DJs.
