Please note:

  • These are general rules only and can change at any given time.
  • Always check with your local council to see if there are any extra electric fencing regulations regarding your local area.
  • Always make sure the products you purchase meet Australian standards.
  • Purchasing from a reputable Australian manufacturer will generally ensure you are ensuring the safety of others in relation to electrical devices that you are responsible for.

Barbed wire and electric fencing

Barbed wire or razor wire must never be electrified by an electric fence energiser.

If you need to electric fence around barbed wire ensure you use sufficient "offset" insulators to minimize the risk off animals and people becoming entangle on the barbed wire. Over exposure to electrical fence shock can be harmful and at the worst fatal.

A non-electrified fence incorporating barbed or razor wire may be used to support one or more off-set electrified wires of an electric fence. The supporting devices for the electrified wires must be constructed so as to ensure that these wires are positioned at a minimum distance of 150mm from the vertical plane of the non-electrified wires. The barb or razor wire is to be earthed at regular intervals in accordance with earthing recommendations.

Electric fence earth systems

A distance of a least 10 meters must be maintained between the energisers earth electrode and any
other earthing system connected parts—for example household mains power protective earth or telecommunication
system earth.

Electric fence connection leads

Electric fence connecting leads located inside buildings must be effectively insulated from the earthed structural parts of the building—example use suitable high voltage insulated cable. Important : always ensure metal parts of the building are effectively earthed.

Electric fence connecting leads located underground must be run in suitable conduit of insulating material or high voltage cable to be used. Care must be taken to ensure that the effects of animal hooves or vehicle wheels (e.g. tractor) sinking into ground cannot damage connecting leads.

Electric fence connecting leads must not be installed in the same conduit as the mains power supply wiring, communication cables or data cables.

If electric fence connecting leads and wires are installed near an overhead power line, their height above the ground must not exceed 3 meters. This height applies either side of the orthogonal projection of the outermost conductors of the power line on the ground surface, for a distance of ;-
- 2 meters for power lines operating at nominal voltage not exceeding 1000V.
- 15 meters for power lines operating at a nominal voltage exceeding 1000V

Overhead power lines and electric fences

Crossing with overhead power lines must be avoided wherever possible. If such a crossing cannot be avoided it must be made underneath the power line and as near as possible at right angles to it.

If electric fence connecting leads and wires are installed near an overhead power line, the clearances must not be less than indicated in the table above.

If electric fence connecting leads and wires are installed near an overhead power line, their height above the ground must not exceed 3 meters. This height applies either side of the orthogonal projection of the outermost conductors of the power line on the ground surface, for a distance of ;-
- 2 meters for power lines operating at nominal voltage not exceeding 1000V.
- 15 meters for power lines operating at a nominal voltage exceeding 1000V

Electric fence for pets, birds and small animals

Electric fences intended for deterring birds, household pet containment or training animals such as cows need only be supplied from a low output energiser to obtain satisfactory and safe performance.

Electric fences intended for deterring birds from roosting on buildings, no electric fence wire shall be connected to the energiser earth electrode. A warning sign must be fitted to every point where a person or persons may gain access to the conductors.

Electric fence warning signs

Electric fences intended for deterring birds from roosting on buildings, no electric fence wire shall be connected to the energiser earth electrode. A warning sign must be fitted to every point where a person or persons may gain access to the conductors.

Where an electric fence crosses a public pathway, a non-electrified gate must be incorporated in the electric fence at that point or a crossing by means of stiles must be provided. At any such crossing, the adjacent electrified wires must carry warning signs.

Any part of an electric fence that is installed along a public road or pathway must be identified at frequent intervals by warning signs securely fastened to the fence posts or firmly clamped to the
fence wires. The size of the warning sign must be at least 100mm x 200mm. The background colour of both sides of the warning sign is to be yellow. The inscription on the sign is to be black and shall be either the symbol shown (fig 1 ) or the words - “WARNING - ELECTRIC FENCE”.

The lettering must be indelible, be on both sides of the sign and in letters not less than 25mm in height.

Electric fencing around public access areas

Where an electric fence crosses a public pathway, a non-electrified gate must be incorporated in the electric fence at that point or a crossing by means of stiles must be provided. At any such crossing, the adjacent electrified wires must carry warning signs.

Any part of an electric fence that is installed along a public road or pathway must be identified at frequent intervals by warning signs securely fastened to the fence posts or firmly clamped to the fence wires.
The size of the warning sign must be at least 100mm x 200mm.
The background colour of both sides of the warning sign is to be yellow. The inscription on the sign is to be black and shall be either the symbol shown (fig 1 ) or the words - “WARNING - ELECTRIC FENCE”.
