Choosing 1650mm Star Pickets for Rural Fences

A star picket that is too short can leave a fence feeling loose from day one. One that is longer than the job requires can add unnecessary cost and make installation harder work. 1650mm star pickets are a useful middle-ground option for many rural fencing jobs, but they need to suit the fence height, ground conditions and stock pressure on your property.

For acreage owners, farmers and contractors, the right picket length is not just about what is available on the day. It affects how well the fence holds its line through wet weather, dry ground movement and the occasional animal leaning where it should not.

Where 1650mm star pickets fit best

A 1650mm star picket is commonly used as an intermediate post in post-and-wire, plain-wire, electric or mesh-style rural fence systems. It can suit general boundary fencing, internal paddock divisions, laneways and areas where a modest fence height is needed above ground with enough length driven into the soil for support.

The key word is intermediate. Star pickets help carry and maintain the fence line between properly built end assemblies, corner posts and strainers. They are not a replacement for substantial strainer posts where wire tension changes direction, finishes, rises sharply or passes through a gateway.

Their suitability depends on the fence design. A lightly loaded electric offset fence may need less holding power than a livestock fence carrying several tensioned wires. Horse fencing also calls for careful planning, as visibility, wire type, fence height and the risk of horses pushing or running into a fence all matter. In those cases, the picket is only one part of a system that must be thought through properly.

Start with finished fence height and driven depth

The simplest way to choose a picket length is to work backwards from the finished fence height. First decide how much picket needs to remain above ground to support the wires, then allow enough length below ground to keep it stable.

There is no single depth that suits every block. Firm clay, compacted ground and shallow rocky country behave very differently from soft, wet or recently worked soil. On a level, well-drained paddock, a 1650mm picket may provide a sensible balance for a standard-height fence. On loose ground, a steep slope or a location exposed to livestock pressure, it may be worth using a longer picket, reducing spacing or changing the overall fence design.

Do not judge depth by eye alone. Drive pickets consistently, check the fence line as you go, and keep the tops at an even level where practical. A string line or laser level can be worthwhile on long, visible runs. Small inconsistencies become obvious once wire is tensioned.

Ground conditions can change within one fence line

Many Yarra Valley properties have more than one soil type in the same paddock. You may start in firm ground near a shed, hit softer country around a drainage line, then strike rock higher up the hill. Treating every section exactly the same can lead to weak spots.

If a picket will not drive cleanly because of rock, forcing it can bend the picket or leave it poorly seated. It may be better to adjust the position slightly, pre-drill where appropriate, or reconsider the post arrangement for that section. Likewise, if a picket sinks too easily in soft ground, closer spacing or a longer picket may be the better answer.

Match picket spacing to the job, not a rough guess

Star picket spacing is often where otherwise decent fence work starts to lose shape. Wider spacing reduces materials and installation time, but it can allow wires or mesh to sag between posts. Closer spacing improves support but costs more and may not be needed on every run.

The right spacing depends on the wire or mesh being used, terrain, fence height and the animals being contained or excluded. Changes in direction, dips, crests and gateways usually require more attention than a long, straight, level run. A fence that looks fine across flat ground can become slack and uneven as soon as it crosses a gully.

For a tensioned wire fence, establish strong strainers first, set the line accurately, and install intermediate pickets in a way that keeps the wires following the intended profile. Do not expect star pickets to correct a poorly planned line after the fact.

Check the picket profile, weight and condition

Not all star pickets are the same. Length is only one part of the decision. Picket weight, steel profile, hole placement and protective finish can affect how they perform and how easy they are to work with.

A heavier-duty picket may be more suitable where there is higher stock pressure, difficult terrain or demanding installation conditions. A lighter picket can be practical for lower-load applications, provided it matches the job. The sensible approach is to look at the whole fence rather than buying on length alone.

Before collecting or accepting pickets, check that they are straight and that the clips or holes are suitable for how you plan to attach wire. If using electric fencing components, make sure the intended arrangement maintains proper separation and avoids earthing out on the steel picket. If pickets are galvanised or coated, avoid damaging the finish unnecessarily during handling and driving, as damaged areas can corrode sooner over time.

A purpose-made post driver is safer and more effective than striking the top directly with an improvised tool. Wear gloves, eye protection and suitable boots, and take care around overhead powerlines and uneven ground. For a substantial fencing project, machinery and the right driving equipment can save a great deal of time and reduce fatigue.

When 1800mm pickets may be the better choice

A 1650mm option is not automatically right simply because it is common. An 1800mm star picket can be a better fit where you need greater height above ground, deeper embedment, wider spacing with added support, or extra confidence in softer soils.

Longer pickets are also worth considering on sloping blocks where finished fence height needs to stay more consistent, or where the fence carries more load. The trade-off is straightforward: they cost more, weigh more and require more effort to drive. Still, using the right picket at the outset is generally cheaper than returning to reinforce a fence that has started to lean or sag.

Conversely, choosing the longer option everywhere may not be necessary. A property can have different fencing needs around the same block, and using the same specification for every paddock is not always the most economical outcome.

Buying 1650mm star pickets for a planned job

Before purchasing, work out the lineal metres of fencing, the likely picket spacing, and the extra pickets needed for changes in direction, uneven country and future repairs. It is sensible to allow a small margin rather than finishing a long way from the gate with one or two pickets short.

Think about transport as well. Long steel pickets need to be properly secured on a trailer, ute or suitable roof-rack system, with any overhang managed safely and legally. For larger quantities, collection arrangements and suitable delivery can make a meaningful difference to the overall job.

Yarra Valley Rural Fencing has selected 1650mm and 1800mm star pickets available for direct purchase while stocks last. These are available for customers needing these particular products, rather than as part of a general fencing supply range. It is worth confirming quantity, collection timing and whether the pickets suit your intended fence before making the trip.

A good fence line begins before the first picket is driven

Walk the line first. Look for wet patches, rock, gullies, old fence debris, vehicle crossings and places where animals naturally congregate. Those details tell you whether 1650mm star pickets will do the job comfortably or whether part of the fence needs a different approach.

A well-chosen picket will not compensate for weak strainers or poor wire tension, but it will help a properly planned fence stay straight, safe and useful for years. If the ground or stock demands are uncertain, getting practical advice before the materials are loaded is time well spent.
