Survey and Mapping Infrastructure Act 2003Survey and Mapping Infrastructure Regulation 2024Part 1Preliminary1Short titleThis regulation may be cited as the Survey and Mapping Infrastructure Regulation 2024.2CommencementThis regulation commences on 1 September 2024.3DefinitionsThe dictionary in schedule 2 defines particular words used in this regulation.4References to cadastral surveyIn this regulation, if the context permits, a reference to a cadastral survey includes a reference to a survey commonly called an identification survey in the surveying profession.Part 2Principles to be applied in carrying out surveysDivision 1All surveys5Importance of State survey and mapping infrastructureThe State survey and mapping infrastructure is of value to the community because it contributes to the State’s economic, environmental and social development.6How survey contributes to State survey and mapping infrastructureA survey contributes to the State survey and mapping infrastructure by, for example, ensuring each of the following for the survey—

(a)survey observations achieve an acceptable level of survey quality;

(b)survey marks placed, or survey marks used as reference points for the survey, provide permanent physical evidence of the survey;

(c)the physical integrity of the survey marks used are appropriate for the survey’s intended purpose;

(d)survey observations made and survey marks placed comply with the relevant survey standard;

(e)survey records for the survey include a clear description of the survey marks placed;

(f)if a survey mark from another survey has been incorrectly placed or disturbed, details of the mark are recorded in an appropriate document;Examples of an appropriate document—

•a State dataset

•the land registry

(g)relevant information about the survey and the survey marks placed are recorded in a State dataset;

(h)the surveyor for the survey accepts responsibility for the survey quality of the survey.

7When survey is of value for survey and mapping infrastructure purpose(1)A survey is of value for a survey and mapping infrastructure purpose if, for example, the survey—

(a)produces information in a form that can be recorded in a State dataset; or

(b)places permanent survey marks; or

(c)makes measurements between permanent survey marks; or

(d)makes measurements that establish the relationship between the geodetic reference framework and a subsidiary framework.Example of a subsidiary framework—cadastral boundary system

(2)Subsection (1) does not limit the power of—

(a)the chief executive in deciding, under section 34(1), 51(3)(b) or 56(1) of the Act, whether a survey mark, or information about a survey, is of value for a survey and mapping infrastructure purpose; or

(b)a surveyor in deciding, under section 55(1) of the Act, whether a survey is of value for a survey and mapping infrastructure purpose.

8Intended purpose of survey(1)A survey must be carried out in a way that achieves the survey’s intended purpose.(2)The survey’s intended purpose may be achieved by, for example—

(a)depicting on the plan of survey the spatial location, and the extent of, the features surveyed; and

(b)establishing appropriate survey marks for the survey by, for example—

(i)placing survey marks that comply with the relevant survey standard; or

(ii)using existing survey marks as reference points; and

(c)achieving a level of survey quality appropriate for the survey’s intended purpose; and

(d)identifying, describing and depicting, as appropriate, natural features that are tidal boundaries or non-tidal boundaries of land.

9Integrating survey and mapping information(1)A survey must be capable of being integrated with other surveys.(2)The integration may be achieved by, for example, ensuring appropriate connections are made between the survey and the following when carrying out the survey—

(a)the geodetic reference framework;

(b)a subsidiary framework;Example—cadastral boundary system

(c)a natural feature forming a boundary of land, including, if appropriate, the former location of a natural feature if the former location still forms a boundary of land;

(d)a permanent improvement on the land.

Division 2Cadastral surveys10Application of division(1)This division applies to a cadastral survey(2)This division applies in addition to, and does not limit, division 1.11How cadastral survey contributes to cadastral boundary systemA cadastral survey contributes to the cadastral boundary system by, for example, ensuring each of the following for the survey—

(a)survey observations achieve an acceptable level of survey quality;

(b)survey marks placed, or survey marks used as reference points for the survey, provide permanent physical evidence of the survey;

(g)survey records for the survey are kept in—

(i)a State dataset; or

(ii)the land registry;

(h)the cadastral surveyor for the survey—

(i)accepts responsibility for the survey quality of the survey; and

(ii)keeps the survey records for the survey in a form suitable as a record of the survey.

12Boundary locations(1)The plan of survey for a cadastral survey must, for a parcel of land surveyed—

(a)describe and show the location of each existing boundary of the land; and

(b)if the survey is carried out for registering an interest in the land—describe and show each boundary of the land the subject of the interest.

(2)A boundary of land is shown on the plan by recording—

(a)all of the following things used as reference points for the survey—

(i)permanent improvements on the land;

(ii)existing survey marks;

(iii)survey marks placed in carrying out the survey; and

(b)the length and direction of the boundary.

(3)A boundary of land must be marked on the land in a way that a person on the land can identify the boundary.(4)However, subsection (3) does not apply if—

(a)the client of the surveyor marking the boundary gives the surveyor written notice that the client does not require the boundary to be marked as required by subsection (3); and

(b)the surveyor complies with the relevant survey standard when marking the boundary of land; and

(c)the reference points used for the survey include a recognised permanent survey mark.

13Taking account of parties’ rights and obligations(1)A cadastral surveyor carrying out a cadastral survey must, in identifying or marking a boundary of land, take account of the rights and obligations of each party affected by the boundary.Examples of a party affected by the boundary—

•an owner of land sharing the boundary

•an owner of land near the boundary if the owner’s understanding of the position of the boundaries of the owner’s land may change as a result of reinstating the boundary

•an owner of land benefited by an easement if the owner’s understanding of the position of the boundaries of the easement may change as a result of reinstating the boundary

(2)The affected parties rights and obligations may be taken account of by, for example, ensuring each of the following for the cadastral survey—

(a)cadastral boundaries are reinstated in accordance with the hierarchy of reinstatement evidence;

(b)cadastral boundaries are defined by abuttals with no gaps between, or overlaps of, the boundaries;

(c)any natural feature forming a boundary of land is clearly described on the plan of survey for the cadastral survey and the feature’s position is shown on the plan;

(d)if there is an apparent irregularity in information recorded for an existing survey mark, the irregularity is recorded in—

(i)a State dataset; or

(ii)the land registry;

Example of an apparent irregularity—Observations made by the surveyor relating to a survey mark differ from the information recorded for the mark in a State dataset.

(e)any encroachment is identified and, if the encroachment is substantial, each owner of land affected by the encroachment is notified.

31Additional information about applicability of cross-section diagrams(1)For any valley, a particular valley reach could contain a section of valley reach, or a section of watercourse within a section of valley reach that may be different to a valley reach and watercourse cross-section depicted in schedule 1, parts 2, 3 and 4.Example—The cross-section of part of a middle valley reach of a particular watercourse might more closely resemble what is typical for an upper valley reach cross-section, and the cross-section of part of a lower valley reach of a particular watercourse might more closely resemble what is typical for a middle valley reach cross-section.(2)Accordingly, a cross-section diagram could be used to help in the location of a non-tidal boundary (watercourse), regardless of the valley reach in which the section of watercourse under consideration is located.32References to valley margins(1)For schedule 1, a reference to a valley margin in relation to a valley drained by a watercourse is taken to be a reference to the bedrock feature that forms a lateral extent of the valley floor.(2)A valley margin may consist of a hill, cliff, ridge or mountain.(3)Whether a valley margin is a hill, cliff, ridge or mountain will depend on where the valley margin is situated in the valley.Example—A valley margin in an upper valley reach could be a mountain but, in a lower valley reach, a valley margin is likely to be no higher than a ridge.33References to terraces(1)For schedule 1, a reference to a terrace in relation to a valley drained by a watercourse is taken to be a reference to an abandoned floodplain that is situated above an active floodplain associated with the watercourse.(2)A terrace is formed when floodplains are abandoned during down cutting into the valley floor by base level change in the form of tectonic activity, by shifts in sediment load or by changes in the flow regime of the watercourse.Part 6Repeal34RepealThe Survey and Mapping Infrastructure Regulation 2014, SL No. 182 is repealed.Schedule 1Valley reachessections 27 to 30Part 1Overview of valley reachesDiagram A—Overview of valley reachesPart 2Upper valley reachExplanation of upper valley reach and associated watercourseThe upper valley reach of a valley drained by a watercourse is typically located in the most elevated parts of the watercourse catchment, often near the catchment’s watershed. The valley floor is typically quite narrow, characterised by gorges and in some places is only as wide as the watercourse itself. The valley floor is typically quite steep, characterised by waterfalls and cascades. The general direction and location of the reach is dictated by the valley margins that appear as significant geomorphic features.The watercourse is typically narrow and deep with a V-shaped profile carved into the bedrock. The location of the watercourse within the narrow valley floor is generally dictated by the valley margins. The flow in the watercourse has high velocity and high energy, resulting in high erosive power. High flow events are confined within the watercourse by the adjoining valley margins. Past flow levels are often evidenced by scour marks on the valley margin or the deposition of lighter material, including, for example, sands and twigs, carried by the flow. The bed and banks of the watercourse typically consist of bedrock and very coarse material, including boulders, cobbles and gravel. The movement and deposition of material happens primarily in periods of high flow. Flow tends to respond directly to rainfall events and during dry periods there is little or no base flow. Vegetation within or along the watercourse is often sparse or immature due to the regular scouring caused by high flow energy or by the absence of deep soil profiles.Where the watercourse is wider, it could have a narrow bench adjacent to one bank or the other. These benches are typically made of finer materials, commonly cobbles and gravel. These benches tend to be short in length and disconnected, and alternate from one side of the watercourse to the other as the flow rebounds from one valley margin to the other. These benches are regularly reshaped by flow events.Diagram B—Cross-sectional view of an upper valley reachDiagram C—Cross-sectional view of a watercourse in an upper valley reachPart 3Middle valley reachExplanation of middle valley reach and associated watercourseThe middle valley reach of a valley drained by a watercourse is typically located in the watercourse catchment’s pediment or foot hills. The middle valley reach is at a higher elevation than the lower valley reach but is not as high as the upper valley reach. The valley floor is typically of moderate width, and is characterised by narrow floodplains between valley margins of fringing hills, terraces and low ridges. The valley floor has a moderate grade, characterised by a meandering watercourse and occasional cascades. The valley floor is typically comprised of ancient sediments deposited by the watercourse in earlier geological periods, and can be interrupted by occasional bedrock ridges or bars that are exposed in the watercourse.The watercourse carries flow from several tributaries and so is typically deeper and wider than in the upper valley reach. The location of the watercourse within the valley floor is generally dictated by its meander pattern and is occasionally bounded by the valley margin. The flow in the watercourse has less energy and is not as fast as in the upper valley reach. However, it has enough energy to transport sediment eroded in the upper valley reach down to the lower valley reach. Much of the sediment being transported is temporarily stored in the watercourse (typically as in-stream benches and islands) or on adjacent floodplains before being further eroded and transported downstream in subsequent high flow events.A number of benches are typical in the watercourse, created by the mixture of flow size and frequency. The lower, narrower channel of the watercourse is shaped by the more frequent, smaller flows and the wider, deeper channel of the watercourse is shaped by less frequent large flows. High flow events commonly erupt from the watercourse onto the adjacent floodplain. The bed and banks of the watercourse typically consist of medium sized material, such as cobbles, gravel and sand. Subject always to long-term weather cycles, almost perennial base flows occur because of the slow drainage of upper sections of the middle valley reach and groundwater inflows from alluvial floodplain aquifers along the watercourse. Vegetation within or along the watercourse is well established because of the reliable base flows and stable channel profile.Diagram D—Cross-sectional view of a middle valley reachDiagram E—Cross-sectional view of a watercourse in a middle valley reachPart 4Lower valley reachExplanation of lower valley reach and associated watercourseThe lower valley reach of a valley drained by a watercourse is typically located in the watercourse catchment’s lowest elevations, generally immediately upstream of where the watercourse becomes tidal or where it flows into a natural terminal lake. The valley floor is quite broad, characterised by extensive floodplains between distant valley margins of fringing hills and low ridges. The valley floor has a low gradient, characterised by a strongly meandering watercourse with ox-bows and occasional anabranches. The valley floor is typically comprised of ancient sediments deposited by the watercourse in earlier geological periods.The watercourse gradient is quite low, resulting in slow moving flow. However, the watercourse is now carrying water from all upstream reaches and so dissipates this kinetic energy by meandering across the valley floor, eroding and depositing sediment along the way. This results in a comparatively wide, shallow channel, often with large sediment accumulations such as in-stream benches and islands. Sediment that makes up the channel of the watercourse and adjoining floodplains tends to be fine, commonly gravel, sand and silt, with low resistance to erosion. Large flows result in floods that spread across the floodplains, depositing fine sediment. Perennial base flows occur because of the slow drainage of upper sections of the lower valley reach and groundwater inflows from alluvial floodplain aquifers along the watercourse. Vegetation within or along the watercourse is well established due to the reliable base flows and stable channel profile.Diagram F—Cross-sectional view of a lower valley reachDiagram G—Cross-sectional view of a watercourse in a lower valley reachDiagram H—Cross-sectional view of a lower valley reach with multiple watercoursesDiagram I—Cross-sectional view of multiple watercourses in a lower valley reachSchedule 2Dictionarysection 3cadastral boundary system means the following—
