KBM1993, Duffy, ACT - Australia/NZ Benchmarks on Waymarking.com

A kerb bench mark on the corner of Somerset Street and Moogerah Street in Duffy. The metal disk is located in the kerb on the eastern side of Moogerah Street.

This is the closest KBM to my house. Well within line of site to precisely determine the seat height of the couch in my lounge room ;-)

Acording to the ACT mapi website.

Kerb Bench Marks (KBM) are placed in the kerbs throughout urban Canberra. They consist of a rectangular brass casting with a nipple and number and are usually levelled to class LC Order L3 standards of accuracy. (Many kerbs have moved and differences of more than 3 centimetres have been found). All KBM levels are on the Australian Height Datum (AHD71). Precise Bench Marks (PBMs) are listed in the KBM register under their number (for example, PBM13 is KBM13). PBMs are precast concrete blocks that were part of earlier Imperial levelling network on an earlier Canberra datum: Precise Datum or PD. (To convert: PD value: 1.07 feet x 0.3048 equals AHD value).
