Permanent marks in land surveying are fixed points on the ground used as reference points for measuring and mapping land boundaries and features. These marks are typically made of durable materials such as concrete, metal, or stone to ensure they last for many years.

Historically, permanent marks have played a crucial role in land surveying by providing consistent, reliable points from which land measurements can be made. This has allowed for the accurate mapping of land boundaries, ownership, and topographical features, which is essential for land development, construction, and legal documentation. The use of permanent marks dates back to ancient times, reflecting the long-standing human need to define and understand the land we live on.

(Photos captured by Daniel, April 2023) 

In the historic colonial town of Ross, central Tasmania a remarkably well-preserved survey mark was found (Top Left). The first recorded surveys of this area were made over 200 years ago by First Government Surveyor Charles Grimes along the Macquarie River in 1807. The second mark (Top Right) was found at Skeleton Bay on the bay of fires. A more recent mark, the red paint, still stands to this day.

This permanent mark was captured at the Mount Dandenong observatory. The original permanent mark survey described it as a trig plaque on top of a concrete pillar, placed before 1982. Interestingly, Charles Grimes was the first surveyor to do the first complete survey of Port Philip

Permanent Mark at Mount Gravatt Outlook, installed in 1961, has been used by Brisbane surveyors for over 60 years, most notably in 1971, 2009 and 2019. A survey from 2001 tells us that it is a brass plug on top of the directional pillar at the peak of Mount Gravatt lookout.
