Southport asks more of a boundary survey than almost anywhere else on the coast. The suburb holds the Gold Coast’s central business district, the hospital and university precinct, canal and Broadwater frontage, and streets of ordinary detached houses on allotments created a century ago, sometimes within a few hundred metres of each other. A boundary here might be a straight line between two timber cottages, a revetment wall standing in tidal water, or a line that has to be resolved before a tower can be set out on it. A boundary survey answers the question properly. A registered cadastral surveyor obtains the title and the original survey plans, recovers the marks that still exist in the surrounding streets, and re-establishes and pegs the corners of the lot.
Two things complicate the work in Southport. The first is the ground itself. A large part of the low lying suburb is reclaimed, canal cut or filled land, and where a property meets water the boundary is not a fence line but a defined position that may sit somewhere quite different from the revetment wall in front of it. The second is how many times the same land has been reorganised. Original small allotments have been amalgamated, resubdivided, built over and converted into community titles schemes across several generations of development, and the further a parcel has travelled from its original plan the more carefully the boundary has to be reconstructed.
Whatever is unresolved on a site becomes the new owner’s problem on settlement, and in Southport the sums involved are rarely small. Surveying during the contract period tells you the actual dimensions and area of the lot, whether the fences, walls and driveways match the title, and what easements or covenants burden the land.
On the older residential streets the usual finds are driveways shared across a boundary, sheds and garages built to or over the line, and services running through a neighbouring lot without an easement to protect them. On waterfront and canal properties the questions are different again, and they concern where the property actually stops, who owns and maintains the revetment wall, and whether the pontoon, jetty or ramp in front of it is authorised. Our article on when and why you need a boundary survey sets out the situations where it is worth doing.
Arguments about a dividing fence rarely settle themselves, because both households are working from impressions rather than evidence. One owner points to where the fence has stood for twenty years. The other repeats what an agent told them at inspection. Neither position can be tested, so the disagreement circles.
Marking the boundary replaces both accounts with a measured line that belongs to neither party. That usually gets a replacement fence agreed and the cost split without further trouble, and it puts you on solid footing if the matter proceeds to a fencing notice under the Neighbourhood Disputes (Dividing Fences and Trees) Act or to QCAT. It matters more where the dividing structure is a masonry wall, a retaining wall or a revetment, because responsibility and replacement cost both depend on which side of the line it sits.
Encroachments in Southport cover a wide range. On the residential streets it is carports, garages, awnings, eaves, sheds, pools and fences built off the wrong reference. On the commercial and mixed use blocks it is basement walls, awnings over footpaths, fire stairs, service ducts, signage and balconies projecting from buildings that were designed before the site was accurately surveyed. Where lots meet public land, encroachments onto road reserve, park or esplanade are common and are usually only discovered when someone tries to develop or sell.
An identification survey records exactly where every relevant structure sits in relation to the true boundary, which is where any resolution begins. Depending on what the survey shows, the outcome may be a written agreement, an easement, a lease of the affected area, a design change or removal.
This is where Southport differs most from an ordinary suburb. Where a lot fronts the Broadwater, the Nerang River or a canal, the boundary is defined by the original survey and by the tidal boundary rules that apply to that parcel, not by the visible edge of the water and not automatically by the revetment wall. Walls get built slightly inside or slightly outside the line. Some sit on the boundary. Fill and erosion change the appearance of the edge without changing the title.
The practical questions this raises come up constantly. Owners want to know whether the wall they are being asked to repair is theirs. Buyers want to know whether the land they are paying for extends to the water. Anyone building near the frontage needs the boundary and the levels before a designer starts, because setbacks and the location of pontoons, ramps and jetties are all measured from a line that has to be established rather than assumed. This work also needs accurate levels tied to Australian Height Datum, which matters on land subject to storm tide and flood.
A large share of Southport is held under community titles rather than a standard freehold lot, and the survey questions change accordingly. Where a duplex, townhouse project or apartment building is being created, a building format plan defines the individual lots and the common property. Existing schemes often need exclusive use plans prepared to formalise car spaces, storage areas, courtyards and balconies that have been used informally for years, which is the sort of thing a body corporate deals with when a resolution is put to a general meeting. For commercial and retail buildings we prepare lease surveys to define and document tenancy areas.
Setbacks, site cover, height and boundary clearances are all dimensioned from the boundary, so an inaccurate line flows straight through the design and shows up when it is expensive to fix.
A detail and contour survey alongside the boundary work gives your designer the existing structures, levels, contours, visible services, trees and neighbouring buildings. For refurbishment and adaptive reuse of existing commercial buildings, 3D scanning captures the structure as it stands and delivers it as point cloud data rather than a set of assumed dimensions. Where lots are being amalgamated or reconfigured, a subdivision survey is built on the re-established boundaries, and our town planners can review the applicable planning framework before a design is committed to, which in central Southport means checking whether the site falls inside the Priority Development Area and is assessed under its development scheme rather than the City Plan. Once construction starts, the same boundaries carry into the set out, as constructed survey and Form 12.
Survey My Block is a Registered Consulting Cadastral Surveyor Organisation with the Surveyors Board of Queensland, working across Southport and the central Gold Coast including Labrador, Ashmore, Molendinar, Parkwood, Benowa, Bundall, Main Beach, Surfers Paradise and Biggera Waters.
A boundary survey with us covers the title and survey record search, the field work to recover the evidence and mark your corners, and a plan showing the boundary against the fences, walls and structures on the site. We also carry out identification surveys, detail and contour surveys, 3D scanning, building format and exclusive use plans, lease surveys, subdivision surveys, construction set out and Form 12s throughout Southport. Tell us about the property and we will explain what is involved and what it will cost, either by getting in touch or by reading our guide to what affects the price of a survey.
In Queensland, a survey of existing property boundaries is commonly called an identification survey. A registered cadastral surveyor examines survey records and physical evidence to identify, re-establish and, where appropriate, mark your property boundaries. An identification survey confirms existing boundaries, it does not create or alter property interests.
We recommend a boundary survey before installing or replacing a fence, constructing a retaining wall, building an extension, or carrying out other work close to a property boundary. It is also useful when purchasing or developing property, investigating a possible encroachment, or resolving uncertainty between neighbours.
Not necessarily. Fences, retaining walls and other improvements are sometimes built away from the true boundary, and the boundary cannot be reliably located by measuring from the kerb. GPS apps, Queensland Globe and online property maps are also not authoritative sources for locating boundaries on the ground. A cadastral survey is required to establish the boundary accurately
The surveyor will review the relevant title and survey information, undertake field measurements and reinstate the surveyed boundaries. Depending on the scope and site conditions, boundary corners may be marked or re-marked, and the survey plan may show relevant fences, retaining walls, buildings and encroachments in relation to the boundary.
A boundary survey provides independent professional evidence showing where the boundary is located and how nearby fences, walls or structures relate to it. However, the survey itself does not determine who is responsible for an encroachment or compel someone to relocate a structure. Where an affected improvement or encroachment is identified, the surveyor may be required to notify the affected landholder, and unresolved disputes may require negotiation, mediation or legal advice.
