The prospect of Eastman's release earlier this year prompted warnings of his continuing danger from former police and prosecutors involved in the original investigation and 1995 trial.

But Eastman has not proved the handful that some had predicted.

He has not been picked up on a single breach of his bail conditions, and has kept quiet as prosecutors decide whether they should try him again for the 1989 killing of ACT police chief and Australian Federal Police Assistant Commissioner Colin Stanley Winchester.

His whereabouts continues to be kept relatively secret, and sightings have been few and far between.

The Director of Public Prosecutions confirmed this week that Eastman had not come to the office's attention for any breaches or fresh offences since his release on August 22.

Police declined to comment.

Any indication about whether the DPP would pursue another trial was still at least a month away.

The DPP has been trawling over evidence in the Winchester case, including new secret claims that could point to the involvement of the Calabrian Mafia, to try and work out whether a new trial is possible.

The new evidence suggesting Mafia involvement has the potential to build an alternative hypothesis for the killing, which is consistent with Eastman's innocence.

But it was only handed to the DPP earlier this month, following repeated refusals by the AFP and Victorian Police to give access for fear they would breach court orders and endanger the life of an informant.

Prosecutors have committed to giving the court an "update" in December on how they are progressing with a decision on a re-trial of Eastman.

But they've told the court that it was unlikely they would have made a decision by then.

"The director's very aware of the importance of making a decision as quickly as possible, but there's a lot of material to consider," prosecutor Margaret Jones said earlier this month.

In the meantime, Eastman's Legal Aid lawyers have filed a "no bill" application to try and have the DPP discontinue the charges.

Eastman, as with all ACT prisoners, became eligible for a host of support services upon his release.
