Police are urging residents in Lake Cargelligo and Mount Hope to take "extreme caution" as the hunt for triple murder suspect Julian Ingram (Pierpoint) enters its second week.

Police have also boosted their presence in Lake Cargelligo over the coming days, including with members of the Public Order and Riot Squad.

Western Region Commander, Assistant Commissioner Andrew Holland, said they will help with the manhunt and ensure community saftey.

"We are trying to give reassurance to the community, make them feel as comfortable as possible. But again, they just need to exercise caution," he said during a 1pm press conference on Thursday 29 January.

"(They can) go about their daily business as normal, but be mindful of the fact that there is a person in the community that could cause a threat."

"Our search location is fluid based on the information provided by the public.

"A large number of properties have been searched."

Police have also confirmed a reported sighting of the suspect at Mount Hope, which is roughly 100 kilometres north west of Lake Cargelligo.

The NSW registration is DM-07-GZ.

They said the vehicle may have a Lachlan Shire Council magnet in front of the driver’s door and may have the numbers 1947 above the magnet.
