You do have to register.
The Wall to Wall is to remember Police Officers who have lost their life in the line of duty, like my school class mate Allan MacQueen in NSW a few decades ago.
The Wall to Wall means from the NSW Police Memorial Wall in Hyde Park, Sydney to the National Police Memorial Wall at Lake Burley Griffin near the Carrillion.
Each year, each Police Service from the States and Territories and the Federal Police add any new names to the Wall in Canberra.
I'm pleased to say that when I attended in 2015, there were no new names to add to the Wall.
