The survey of the border of the Federal Capital Territory (now the ACT) is on plan FC18 (13 sheets). Copies of this survey were lodged with the NSW Land Titles Office.

OSGLI keeps the original Field Books of this survey. High-resolution scanned copies of the Field Books are available on the Resources page.

After the 2003 bushfires, the ACT Planning and Land Authority (ACTPLA) surveyed and remarked the most damaged parts of the border. The new border reached from Mt Gingera to Mt Coree along the western border, then north-easterly to One Tree Hill. This area covers approximately 67km in total.

The original survey placed a large reference mark at every mile of the border. This meant each plan of the re-survey generally covered a mile of the border. A registered surveyor signed and fully examined each plan of re-survey. They were also certified by the ACT Surveyor-General and the NSW Surveyor-General. You can use the cadastral information shown on Territory Border Plans to re-establish the ACT/NSW border. Copies of these plans were also lodged with the NSW Land Titles Office and are DPs in that state.

Example: TBP16 Mouat. This is a re-survey from the "15 Mile" mark to the "16 Mile" mark, performed by Mr Surveyor Mouat.
