Police sent to build the peace in Solomon Islands say they're wearing flak jackets after the killing of one of their colleagues this week.
The Deputy Police Commissioner, Sandi Piesley, says assistance mission police are wearing body armour.
The body of the police officer Adam Dunning has been flown to Canberra, ahead of a full funeral at a later date.
Deputy Commissioner Piesley says they're positive about the investigation into how the officer was shot dead in Honiara.
But she wouldn't confirm reports that police had concrete leads and a clear suspect in mind.
"We're very positive in terms of the investigation; we've had a lot of support from the community, and a lot of information coming in, and we're following up on all of those, and yes, in terms of the investigation, I feel quite positive."
