Boundary marks are marks that are specifically used to identify the perimeter boundaries of a parcel of land that forms part of the cadastre. A Surveyor is bound under the Surveying Practice Regulation Act to use a set of approved type of survey marks. These include survey pegs that measure 50 x 75 x 450 mm in size for residential lot boundaries and pegs that measure 75 x 75 x 450 mm for rural lot boundaries. In circumstances where it is impracticable to place a boundary peg other approved survey marks may be used such as drill hole and wings in concrete and stone or galvanised nails in fences if practical. Other survey marks used in construction setout of buildings or roads consist of a multitude of other markings including pegs, star pickets, reo-bars, nails in profiles and wooden stakes.

Before land subdivision can occur the client/landowner needs to ensure that the land is zoned to be further fragmented /subdivided. The interested party can either consult the local Council website or use a local Town planner to find out. Should further subdivision be permissible the next step is to lodge a Development Application (DA) to be lodged with Council. This will require a site plan or a Contour a Detail prepared by a Surveyor to accompany the DA. The DA approval process can take several month before a council approval may be granted, subject to councils conditions of consent. This is often referred to as the Notice of Determination.

A details Survey is a mud map or a representation of all improvements contained on the parcel of land and may at request contain levels and show contours on the survey plan. Contours being a line of equal heights and relate to a specify height datum.
