Traditionally the Katherine service is held at the graveside of Constable William Condon.

The service will be followed by morning tea at the Cemetery Rotunda, hosted by Commander Janelle Tonkin.

All members of the public are invited to attend.

On June 9, 1952, Constable Condon was in Katherine from his usual station of Maranboy, assisting with the Katherine Races, when he was called upon to search for an armed gunman, 23 year-old Terence Stapleton.

About 7.25pm the 29 year-old police officer, married for only 12 months, observed Mr Stapleton in the main street of Katherine.

Without hesitation he approached Mr Stapleton with hands open to show he was unarmed.

But Mr Stapleton produced a firearm and fired twice, killing the young constable.

Constable Condon was posthumously awarded the Queen's Police Medal for Gallantry and a plaque was erected at Katherine police station.

Police across the Territory will pause today to pay tribute to fallen colleagues as part of National Police Remembrance Day commemorations across the Territory.

Each year, September 29 holds a special significance for police throughout Australia, New Zealand, Papua New Guinea, Samoa and the Solomon Islands.

It is a day for police to pause and honour officers whose lives have been lost while performing their duty as a police officer.

The day acknowledges the risks associated with the job and what stepping into the uniform and serving the community represents.

Commissioner of Police Jamie Chalker APM said this year's National Police Remembrance Day was particularly important in light of the tragic loss of four Victorian Police Officers in one incident while on duty in April and a New Zealand officer who was killed in Auckland in June.

"The COVID-19 pandemic has also seen policing at the forefront of not just community safety but also a global health emergency.

"Our police officers were thrust into new roles to engage and enforce new policies and laws governing societal behaviours.

"I am particularly grateful our frontline police officers, staff and volunteers who continue to do an exceptional job in keeping our community safe.

"As we transition to living in a world none of us have experienced before, the new 'normal' so to speak, National Police Remembrance Day allows us to reflect on the role of our police as we serve, protect and uphold the laws.

"In particular, we pay tribute to the men and women in the police service who have made the ultimate sacrifice. Together, we must ensure their legacies are preserved."

The day is marked by the wearing of the traditional blue and white chequerboard ribbon, officially recognised as the symbol of Remembrance Day.
