More than 2,000 police are hitting the road in a motorcycle ride from Sydney to Canberra to honour fallen officers.
The families of slain NSW Police officer Sergeant Geoff Richardson and NSW Police Senior Accountant Curtis Cheng took part in a ceremony at The Domain on Saturday morning ahead of the annual charity ride to Canberra.
NSW Police Commissioner Andrew Scipione said this year's ride held particular significance.
"Unfortunately we'll be adding two names to the wall this year, Curtis Cheng and Geoff Richardson, their families are here with us today, they will be joining us as we travel to Canberra, we remember their respective husbands and we'll pay our respects," Scipione told Macquarie Radio.
The 2-day ride to the National Police Memorial in Canberra pays homage to officers who have died while serving their community. The ride also aims to raise money for police legacies across Australia.
Saturday's convoy leaves after a motorcycle convoy of more than 300 riders departed Melbourne for Canberra on Friday as part of Victoria's contribution to the Ride for Remembrance.
The Victorian motorcyclists are making their way to Canberra and will meet up with the NSW contingent at the National Police Memorial for the remembrance service.
