Exclusion Fencing Planning Guide for Rural Land

A wallaby finding one low spot, rabbits working under a loose edge, or deer pushing through an old corner can undo a lot of work quickly. A good exclusion fencing planning guide starts with the animal causing the problem and the way it is getting onto your property. The fence itself matters, but the layout, ground preparation, gates and ongoing checks are what determine whether it keeps doing its job.

For rural and acreage properties, exclusion fencing is rarely a one-size-fits-all job. A fence that works well around a vineyard, orchard or vegetable patch may not suit a horse property, a livestock paddock or a bush block with steep gullies and regular wildlife movement. Planning properly before posts go in helps avoid costly alterations later.

Start with the problem, not the fence

Before choosing fence height, mesh or electric offsets, be clear about what you are trying to exclude. Deer, kangaroos, wallabies, rabbits, foxes and domestic animals all test fences differently. Some jump, some push through, some dig, and some simply use an open gate as an invitation.

It is also worth separating the main problem from the occasional one. If deer are regularly damaging new plantings, the fence needs to be designed around deer pressure. Building a fence primarily for rabbits because you see one or two occasionally may add cost without delivering much practical value. On the other hand, if rabbits are established along a boundary, a high fence with an unprotected bottom edge will not solve the problem.

Think about what is being protected as well. A full property boundary is one approach, but it is not always the most sensible or affordable one. In some cases, fencing a high-value cropping area, garden, fodder store or regeneration zone gives better value than enclosing every acre.

Walk the proposed fence line

A map is useful, but a proper walk of the line tells you what the job will actually involve. Mark the intended route and look closely at changes in level, wet ground, rocky sections, creek crossings, tracks, established trees and existing fences. These details affect construction time, access and the final cost.

Check for weak points early

Animals tend to find the same weak points people overlook. Low ground at the base of a rise, a washout beside a culvert, a gap under a gate and a section where vegetation pushes against the fence are common trouble spots. If the fence line crosses a drainage channel, plan for water movement without leaving a permanent opening below the fence.

Steep country needs particular attention. A straight, level-looking fence can leave sizeable gaps under the mesh when it follows a slope. The line may need to step with the terrain, use closer post spacing or be adjusted to follow a more workable route. There is usually a trade-off between taking the shortest line and building a fence that can be installed, maintained and kept tight.

Plan access for construction and repairs

Consider how materials, machinery and people will reach the line. A remote back boundary may look simple on paper but become expensive if access is limited by muddy tracks, narrow gateways or thick vegetation. The same question applies after installation. If a fallen branch damages the fence in winter, can you reach it safely to carry out repairs?

Where possible, keep a clear maintenance strip along the fence. Long grass, blackberries and fallen timber make inspections harder and can create pressure points on wire or mesh. Clearing does not have to mean stripping the site bare, but the fence should be visible and accessible enough to check properly.

Match the design to the animal pressure

The right exclusion fence design depends on the target animal, the surrounding land use and the level of pressure on the site. Height is a major consideration for animals that jump or lean over fencing. Mesh opening size and the treatment of the bottom edge matter more where smaller animals are the concern.

For digging animals, the lower section needs to be planned as carefully as the top. Depending on site conditions and the animal being excluded, this may involve burying mesh, returning it outward along the ground, or using another suitable barrier detail. The best option depends on soil type, drainage and how likely the edge is to be disturbed by stock, machinery or water.

Electric fencing can be a useful addition where animals are likely to test the fence, particularly on larger rural properties. It should be treated as part of the overall design rather than a quick fix added at the end. A poorly positioned offset wire or an energiser that is not maintained will not compensate for loose mesh, poor earthworks or an open gateway.

If livestock are also using the paddock, the fence must work for them as well as keeping unwanted animals out. Horses, cattle, sheep and alpacas each place different pressure on a fence. Visibility, safe wire placement, post strength and gate arrangement all need to be considered before construction starts.

Give gates the same attention as the fence

A well-built exclusion fence can be defeated by one gate that does not meet the ground properly. Gates need to be wide enough for the equipment that will use them, including tractors, utes, slashers and horse floats where relevant. They also need a practical method of closing the gap beneath and beside the gate when it is shut.

Consider how often each entrance will be used. A frequently used access point needs to be simple enough that everyone on the property will secure it every time. Complicated arrangements often get bypassed during busy periods. For lesser-used entries, a fixed or lockable barrier may be more suitable than a gate that is regularly left open.

Corner assemblies, end strainers and gate posts deserve proper planning too. These are high-load parts of the fence, especially on long runs and uneven ground. Saving money by underbuilding them can lead to sagging wire and ongoing adjustment work.

Work with the ground, water and neighbouring properties

Exclusion fencing should not create new drainage problems. Water naturally concentrates in low points, and heavy rain can scour soil from under a fence or carry debris into it. Plan drainage crossings so the line can cope with normal flows and be inspected after significant weather.

Check title boundaries before setting out any new boundary fence. Existing fences are not always on the legal line, particularly on older rural properties. If the fence will sit near a neighbour, talk through the route, access needs and vegetation work early. A straightforward conversation before work begins is far easier than sorting out a disagreement once materials are on site.

Vegetation, waterways, wildlife corridors and local planning controls may also affect where and how a fence can be built. This is especially relevant on bush blocks, near creeks or in areas with environmental overlays. If there is any uncertainty, check the relevant requirements before committing to the route.

Budget for the full job, not just the lineal metres

The length of the fence is only one part of the cost. Ground conditions, access, clearing, strainers, gates, drainage details, the selected exclusion method and removal of old fencing can all change the scope. A short fence over steep, rocky country may require more work than a much longer run across open, level ground.

It can be tempting to reduce the specification at corners, gullies or gates to keep the upfront figure down. Those are often the areas where exclusion fencing fails first. If the budget is tight, it may be better to stage the work or focus on the highest-value area rather than compromise the critical details throughout the job.

Prepare for a useful site visit

A site visit is the best time to turn a broad idea into a workable plan. Have a rough property map or aerial image available if possible, and be ready to show where animals are entering, where damage is occurring and how the land is used through the year. Photos of tracks, digging, damaged plants or pressure points can also help identify the right approach.

Before requesting a quote, it helps to have answers to a few practical questions:

• Which animals need to be excluded, and how regularly are they causing damage?

• Is the goal to protect the whole property, one paddock or a smaller high-value area?

• Where will machinery, livestock and people need gate access?

• Are there creeks, gullies, steep sections or difficult access along the route?

• Is there an existing fence worth incorporating, repairing or removing?

A clear brief does not mean you need every detail worked out. It simply gives the fencing contractor a better starting point for recommending a design that suits the property rather than applying a standard layout.
