5 Common Fencing Mistakes That Cost You Thousands

G'day! If you've been around rural properties for any length of time, you've probably seen some absolute shockers when it comes to fencing. We've all driven past paddocks where the fence is sagging like a hammock, or watched gates that swing in the breeze because they weren't hung properly.

After years of helping farmers and property owners across Central West NSW get their fencing right, I've seen the same costly mistakes crop up time and time again. The thing is, these fence building errors don't just look ordinary – they can cost you thousands in repairs, replacement materials, and lost livestock.

Let me share the five biggest fencing mistakes I see, and more importantly, how you can avoid them on your property.

Mistake #1: Skimping on Foundation Work – The 'She'll Be Right' Approach

This is the big one, and probably the most expensive mistake you can make. I can't tell you how many times I've seen blokes rush the groundwork because they're eager to get the fence up and the job done.

Here's what typically happens: you don't dig your strainer post holes deep enough, or you don't use enough concrete, or worse – you skip the concrete altogether and just ram earth around the posts. Everything looks bonzer for the first few months, maybe even the first year. Then the wet season hits, or you get a decent frost, and suddenly your entire fence line is leaning like the Tower of Pisa.

For proper rural fencing, your strainer posts need to go down at least 900mm, and preferably 1.2 metres for heavy-duty applications. Use quality concrete, not just whatever bag was cheapest at the hardware store. A properly set strainer post will last decades – a rushed job will have you back out there with the post-hole digger in two years' time.

The fix: Take your time with the groundwork. It's not glamorous, but it's the foundation of everything that follows.

Mistake #2: Wrong Wire Spacing on Hinged Joint Mesh

Hinged joint mesh is brilliant stuff when it's used correctly, but I see people get the specifications wrong all the time. The classic error is using 6/70/30 mesh (6 horizontal wires, 70cm high, 30cm stays) when you really need 8/90/30 mesh for the job at hand.

I had a client last year who fenced an entire paddock with 6/70/30 mesh to contain sheep. Seemed logical enough – it's cheaper than the heavier grades. Problem was, the lambs could squeeze through the larger gaps at ground level, and within a month, half his flock was wandering the neighbour's lucerne crop. Cost him more in crop damage compensation than he saved on the mesh.

The general rule is simple: 6/70/30 for horses and cattle where you just need a visual barrier, 7/90/30 for sheep and goats, and 8/90/30 for lambs, kids, or anywhere you need maximum security.

The fix: Match your mesh specification to your livestock, not your budget. Getting it right the first time always works out cheaper.

Mistake #3: Inadequate Star Picket Selection

Star pickets cop a real hammering in Australian conditions, but I still see people buying the lightest, cheapest posts they can find. Standard star pickets might save you a few dollars per post, but they're not up to the job in challenging terrain or with heavy mesh.

For serious rural fencing, you want 2.1kg/m heavy-duty star pickets as your standard. They cost a bit more upfront, but they'll stand up to livestock pressure, won't bend when you're driving them in rocky ground, and they'll last years longer than lightweight alternatives.

I've seen entire fence lines fail because someone used lightweight pickets with heavy hinged joint mesh. The posts gradually bend under tension, the fence loses its shape, and before you know it, you're looking at a complete rebuild.

The fix: Invest in heavy-duty star pickets from the start. Your future self will thank you when you're not out there straightening bent posts every few months.

Mistake #4: Poor Wire Tensioning Techniques

This is where a lot of DIY fencing jobs come unstuck. Wire tensioning looks straightforward enough, but there's definitely a knack to it. The most common error is over-tensioning – blokes think that tighter is always better and crank their wire strainers until everything's drum-tight.

Problem is, over-tensioned wire becomes brittle and prone to snapping, especially with plain wire. When one wire snaps under high tension, it often takes others with it, and suddenly you've got a major repair job on your hands.

Whether you're working with barbed wire, plain wire, or the tensioning wire on hinged joint mesh, you want firm tension, not maximum tension. The wire should be tight enough to maintain its line and resist livestock pressure, but with enough give to handle thermal expansion and contraction.

The fix: Learn proper tensioning technique, or better yet, get someone experienced to show you the ropes on your first few fence lines.

Mistake #5: Ignoring Local Conditions and Regulations

Every property is different, and what works on your mate's place down the road might not be right for your situation. I see this particularly with boundary fencing, where people don't check local council requirements or don't consider things like fire management, flood patterns, or wildlife corridors.

In some councils around Central West NSW, there are specific requirements for rural fencing height, setbacks from roads, and materials used in bushfire-prone areas. Getting this wrong can mean expensive modifications down the track, or even fines.

Then there's the practical side – choosing fencing that doesn't suit your land. Putting up a low fence in a flood-prone area where debris will collect, or using mesh fencing where kangaroos regularly travel, can create ongoing headaches.

The fix: Do your homework before you start. Check with your local council, talk to neighbours about what works (and what doesn't), and consider your specific conditions.

Getting It Right From the Start

Look, fencing mistakes happen to the best of us, but the expensive ones are usually avoidable with a bit of planning and the right materials. At Outback Fencing Supplies, we see these same issues crop up regularly, and we're always happy to help customers avoid the common pitfalls.

The key to successful rural fencing is taking your time with planning, investing in quality materials suited to your specific needs, and not cutting corners on the fundamentals. Whether you're fencing a small hobby farm or thousands of acres, these rural fencing tips will save money fencing in the long run.

Remember, a good fence is an investment that should last decades, not something you'll be patching up every couple of years. When you factor in the cost of your time, replacement materials, and potential livestock losses, doing it right the first time is always the most economical approach.
