As part of the Survey Co-ordination Act 1949, any public office, when carrying out a survey which is not a survey as defined under the Surveyors Act, should place Permanent Marks as prescribed by the Act and connect to the State Survey Control. The Survey Co-ordination Regulations came into existence under the Survey Co-Ordination Act 1949 after the publication of Government Gazette 22 June 1951. The Survey Co-ordination Regulations were later amended in Gazette 4 February 1955. As part of the of the amendment it became mandatory that after a proper officer of a public authority has placed a Permanent Mark a sketch plan of the type and position of the mark should be lodged with the Surveyor General.
Permanent Mark Sketch Plans show each permanent survey mark that has been placed by the Surveyor. It shows the map grid of Australian co-ordinates of each mark, with an estimate of how accurate the co-ordinates are. If an accurate Australian Height Datum is determined for a mark then a value is shown.
