Internal Paddock Division — Cheap and Effective Options

Good boundary fences are essential. But the fences that actually improve your productivity are the internal ones — the paddock divisions that let you manage grazing, separate stock classes, and run a rotational system. The good news is that internal fencing doesn't need to be built to boundary-fence standards, and there are some genuinely affordable options.

WHY SUBDIVIDE?

Rotational grazing is one of the easiest ways to improve pasture productivity. Moving stock between smaller paddocks lets pasture recover, reduces selective grazing, and can increase carrying capacity by 20-30% without any other changes. But you need internal fences to make it work.

Even without formal rotational grazing, separating bulls from cows outside joining, keeping weaners away from the main mob, or having a dedicated holding paddock near the yards all require internal fencing.

OPTION 1: PLAIN WIRE FENCE (PERMANENT, CHEAPEST)

A 5-strand plain wire fence is the classic internal division for cattle. No mesh — just five runs of high-tensile wire at graduated heights.

Materials per kilometre:

• HT 2.5mm wire: 5 rolls x $200/1500m = $667 (5km of wire for 1km of fence, assuming some waste)
• Star pickets 180cm at 7m spacing: 143 x $8.40 = $1,201
• Strainer assemblies (4 per km): ~$560
• Clips and sundries: ~$150

Total: approximately $2,580/km or $2.58/m

This is a permanent fence that'll last 20+ years. It won't contain lambs or keep predators out, but for cattle subdivision on an established property, it's the best value going.

OPTION 2: 3-WIRE ELECTRIC (SEMI-PERMANENT)

For trained cattle that already respect electric fences, three strands of electrified wire on insulated posts is cheaper again and very effective.

Materials per kilometre:

• Polywire or HT electric wire: ~$150
• Tread-in posts at 10m spacing: 100 x $4 = $400
• Insulators and connectors: ~$100
• Solar energiser (powers up to 5km): $350-$500 (one-off, covers multiple paddocks)

Total: approximately $1,000-$1,150/km or $1.00-$1.15/m (excluding energiser)

The catch: this requires ongoing maintenance (vegetation control, battery checks) and only works while the energiser is functioning. But for flexible grazing management, it's hard to beat on cost.

OPTION 3: SINGLE-WIRE ELECTRIC (TEMPORARY STRIP GRAZING)

For short-term strip grazing or temporary stock separation, a single strand of polywire on tread-in posts can be set up in an hour and moved daily.

Materials:

• Polywire reel: $30-$50
• Tread-in posts (reusable): 20 x $4 = $80
• Energiser: existing or portable $150-$250

Total: under $200 for reusable equipment

This is not a fence in any permanent sense — it's a stock management tool. But on properties already using electric, it's the cheapest way to control grazing.

OPTION 4: LIGHT MESH FENCE (SHEEP INTERNAL)

For sheep properties where lambs need containing even on internal fences, you need mesh. But you can use lighter specifications than boundary fencing:

• 7/90/30 mesh at $285/200m instead of heavier options
• Picket spacing at 6m instead of 4-5m
• Fewer strainer assemblies (flat ground allows wider spacing)
• Skip the barbed wire if predator pressure is low

Materials per kilometre:

• 7/90/30 mesh: 5 rolls x $285 = $1,425
• Star pickets at 6m: 167 x $8.40 = $1,403
• Strainers (3 per km): ~$420
• Clips and sundries: ~$200

Total: approximately $3,450/km or $3.45/m

Cheaper than a boundary-spec sheep fence ($4.20+/m) but still contains lambs and provides a physical barrier.

OPTION 5: EXISTING FEATURES AS BOUNDARIES

Don't overlook natural features. A creek line, a steep gully, a dense tree line, or an existing laneway can serve as one side of your paddock division, reducing the fencing you actually need to build. One bloke near Manildra saved himself 400m of fencing by using an existing creek as the boundary for two paddocks.

DESIGN TIPS FOR INTERNAL FENCING

Put gates where you actually walk. Internal gates should align with laneways and stock routes so you can move stock easily. A beautifully built internal fence with the gate in the wrong spot is a daily frustration.

Think about water access. Every subdivided paddock needs water. Plan your fencing around existing troughs, dams, or pipe runs.

Leave laneways wide enough. If you're creating a central laneway for stock movement, make it at least 6-8m wide. Narrow laneways cause bottlenecks and stock injuries.

Consider future subdivision. If you might divide a paddock further down the track, put your current strainer assemblies where future fences would tie in.

OPTION 3: TEMPORARY STRIP GRAZING SYSTEMS

For maximum flexibility, temporary electric netting or single-wire systems let you create strip grazing areas that can be moved weekly or even daily. This is particularly effective for intensive rotational grazing on smaller properties or high-value pasture areas.

Electric netting systems cost around $8-12 per metre but are completely portable. A 100-metre roll can create various paddock shapes and sizes, and moves easily with a quad bike or ute. Single-wire systems using lightweight Outback Pickets and polywire cost even less — around $0.50-0.80 per metre — and work well for docile cattle familiar with electric fencing.

PLANNING YOUR SUBDIVISION

Before choosing materials, plan your paddock layout carefully. Aim for paddocks of similar size and carrying capacity, with each having water access or the ability to add portable water points. Consider prevailing winds, natural contours, and existing laneways. A well-planned system of 8-12 paddocks allows for proper rotation timing while keeping infrastructure costs reasonable.

Don't forget about gateways — budget around $80-120 for a basic gate and hardware for each internal gateway. Position gates strategically to allow easy stock movement and machinery access for pasture maintenance.

Labour costs vary significantly depending on terrain and your own capabilities, but expect to spend 1-2 days per kilometre for plain wire fencing, or half that for electric systems on easy ground.

Frequently Asked Questions

How many paddocks do I need for rotational grazing?

A minimum of 4-6 paddocks allows basic rotation, but 8-12 paddocks provides better pasture recovery time and more flexible management options. Start with fewer paddocks and expand the system as budget allows — internal fencing can be added progressively.

Will a 3-wire electric fence hold cattle that haven't seen electric fencing before?

Untrained cattle need introduction to electric fencing in a smaller area first, ideally with a conventional fence backup. Once they've learned to respect the wire, a properly energised 3-wire system is very effective. However, in high-stress situations (mustering, storms), cattle may still challenge electric fences.

What's the most cost-effective approach for a new subdivision system?

Start with one or two key internal fences using plain wire construction — these become the backbone of your system. Add temporary electric divisions as needed for fine-tuning your grazing management. This hybrid approach gives you permanent reliability where needed and flexibility everywhere else.
