Services will be held across the country today to mark National Police Remembrance Day.
The annual event honours officers killed in the line of duty as well officers who lost their lives through illness or other circumstances.
Since the formation of the NSW Police Force in 1862, 254 officers have died in the line duty.
On Wednesday around 70 past and current officers held a special service at the police memorial at Woronora Memorial Park in Sutherland.
The memorial was opened last year and honours 24 NSW Police officers who were killed on duty while serving in the St George, Sutherland and Miranda local area commands.
NSW Police Commissioner, Andrew Scipione joined hundreds of officers at the NSW Police Wall of Remembrance in The Domain this morning.
Commissioner Scipione said National Police Remembrance Day is a time for everyone in the policing family to come together and honour those who have made the ultimate sacrifice.
“National Police Remembrance Day is about recognising the incredible courage of those officers who’ve lost their lives while serving the community of NSW,” he said.
“It is with great sorrow that we pause to remember two of our beloved policing colleagues; Curtis Cheng and Sergeant Geoffrey Richardson.
“Today is about honouring the legacy they leave behind and standing in solidarity with their loved ones who have joined the policing family to mark this solemn occasion.
“The tragedy of their passing is a sober reminder of the continued dangers that thousands of brave men and women face each day in service to the community, where there’s no way of knowing what potential risk they may face.’’
