That's the message from the family of missing Bathurst man, Andrew Russell, who have launched a poster campaign across the city encouraging people to come forward to police.

The family spent all day hanging posters in the CBD, reminding people about Andrew's disappearance and the fact a $750,000 reward, announced two years ago, still stands for information leading to the recovery of his remains,

Andrew's sister, Kiara White, said she would really like to thank some of the amazing stores who allowed them to post a flyer about Andrew in their store.

"It means a lot and we really appreciate it and want to thank these businesses," she said.

On Andrew's Facebook page "Help find Andrew" Ms White said the group will be out and about again shortly to continue to post the flyers and to get the message to every person in Bathurst to come forward even with the smallest amount of information they may have heard or even over heard someone saying.

Anyone interested in helping out can contact Ms White via Andrew's Facebook page. She said they are also happy to send out posters for people to distribute in their area.

She said the family hope they serve as a reminder, especially to those who may not have social media that they are still asking for people to come forward with any information they may have about Andrew's disappearance.

Ms White has said before the family have no doubt there are people in Bathurst who know the truth, and know where Andrew's remains are buried.

"Some of these people have kids now... what they need to remember is Andrew was also someone's child," she said.

"What would they do if this happened to their child?"

Ms White said she just wants to find out where Andrew is and importantly keep him in people's minds. She said she has not given up hope of finding Andrew's remains and having those responsible for his death made accountable.
