3Importance of State survey and mapping infrastructure

The State survey and mapping infrastructure is of value to the community because it contributes to the State’s economic, environmental and social development.

4How a survey contributes to the State survey and mapping infrastructure

A survey contributes to the State survey and mapping infrastructure by, for example, ensuring each of the following—

(a)survey observations for achieving an acceptable level of survey quality are made;

(b)the survey marks placed, or the 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 is appropriate for the survey’s intended purpose;

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

(e)the survey records for the survey contain 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 kept under a registration Act

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

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

5When a survey is of value for a 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.

6Intended 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 extent of the features surveyed; and

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

(i)placing a survey mark of a type complying with the relevant survey standard; or

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

(c)achieving an acceptable level of survey quality that is 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.

7Integrating 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 to 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.

8Application of div 2

This division applies to a cadastral survey in addition to division 1.

9Boundary locations

(1)The plan of 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)each 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 for the marking; and

(c)the reference points used for the survey include a recognised permanent survey mark placed in carrying out a State control survey.

10Taking 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)This may be achieved by, for example, ensuring each of the following—

(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)how to decide the position of a natural feature forming a boundary is recorded 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 kept under a registration Act;

Example of an apparent irregularity—

Observations made by the surveyor relating to the 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.

(3)In this section—

hierarchy of reinstatement evidence means a set of rules recognised in the surveying profession—

(a)for giving weight to evidence of cadastral boundaries; and

(b)used in the reinstatement of cadastral boundaries.

11Importance of cadastral surveys for cadastral boundary system

(1)A cadastral survey contributes to—

(a)the maintenance and improvement of cadastral boundaries throughout the State; and

(b)the information held in—

(i)a State dataset; or

(ii)the land register kept under a registration Act.

(2)This may be achieved by, for example, ensuring each of the following for the survey—

(a)survey observations for achieving an acceptable level of survey quality are made;

(b)survey marks placed, or the 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 is appropriate for the survey’s intended purpose;

(d)the way survey observations are made and survey marks are placed complies with the relevant survey standards;

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

(f)permanent survey marks are placed to assist future reinstatement;

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

(i)a State dataset; or

(ii)the land registry kept under a registration Act;

(h)the cadastral surveyor for the survey—

(i)accepts responsibility for the survey quality; and

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

12Geodetic reference framework

(1)The geodetic reference framework prescribed for section 6 (4) of the Act is—

(a)for latitude and longitude—GDA 94; and

(b)for mapping projection—MGA 94.

(2)In this section—

GDA 94 means the ‘Geocentric Datum of Australia 1994’ (commonly called ‘GDA 94’) notified in the Commonwealth Government Gazette No. GN 35 on 6 September 1995, at page 3369.

(a)the plan must be in the approved form and signed by the surveyor; and

(b)the surveyor must endorse the plan to the effect that it was prepared under this section.

(3)The cadastral surveyor is responsible for the accuracy of the information used for preparing the plan.

17Reinstating existing boundaries

(1)This section applies if a cadastral surveyor carries out, or is responsible for carrying out, a cadastral survey, including a survey commonly called in the surveying profession an identification survey, to find out the position of an existing boundary on land.

28Additional 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 is not typical, having regard to the valley reach and watercourse cross-sections 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.

29Explanation about valley margins

(1) Schedule 1 includes a number of references to valley margins.

(2)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.

(3)A valley margin could consist of a hill, cliff, ridge or mountain, but this will generally vary according to 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.

30Explanation about terraces

(1) Schedule 1 includes a number of references to terraces.

(2)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.

(3)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.

sections 24 to 27

Diagram A—Overview of valley reaches

Explanation of upper valley reach and associated watercourse The 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 C—Cross-sectional view of a watercourse in an upper valley reach

Explanation of middle valley reach and associated watercourse The 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 reach

Diagram E—Cross-sectional view of a watercourse in a middle valley reach

Explanation of lower valley reach and associated watercourse The 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.
