Placement of new marks

Clauses 28 and 29 Surveying Regulation 2006 set out the requirements for the placement of new reference marks in urban and rural subdivisions respectively.

A reference mark may not be connected to:

  • more than one point / corner on the plan
  • any point on the plan greater than 30 metres distant form that mark.

Note The use of a texta pen mark on fence posts etc as reference marks is not acceptable.

Urban surveys

In any urban survey, the survey must:

  • if the land abuts a road have a reference mark at each extremity of the land and at intervals of not more than 100 metres throughout the length of the road frontage of the survey where there are intervening side boundaries, or
  • if the land does not abut a road - have at least 2 reference marks at suitable locations in relation to the land being surveyed.

A reference mark does not need to be placed at the extremity of the land being surveyed if some other reference mark is already placed within 10 metres of that extremity and that reference mark is referenced to that extremity on the survey plan - see cl.28.

Rural surveys

In any rural survey, the survey must:

  • connect or place and connect at least 2 reference marks for each parcel shown on the plan of survey in selected positions suitable for redefinition of the survey.
  • if a boundary (other than a road frontage) exceeds 2,400 metres, place reference marks along the boundary at intervals of not more than 1,500 metres.
  • on road frontage boundaries, place reference marks so as to refer to the terminals of the road surveyed, to each junction or intersection of any roads and in pairs suitable for orientation purposes throughout the whole length of the road in selected positions so that the maximum distance between any 2 successive reference marks does not exceed 1,000 metres - see cl.31(5).

If the land in a new plan is not being subdivided the surveyor must connect or place and connect to 2 reference marks in positions suitable to relocate the survey - see cl.29.
