Installing a flagpole in Australia: permits, footing and site

Putting up a flagpole in Australia touches on state building and planning law, the local council, the ground under the site and the lines above it. The rules differ between states and territories more than for most garden structures: the height up to which a flagpole needs no permit ranges from 3 metres in Western Australia to 10 metres in Queensland and South Australia. This guide gives an overview; the council or a building surveyor can say what applies to a particular site.

When a permit is needed

Each state and territory lists minor structures that need no building permit or development approval. Flagpoles are among them, with limits:

• New South Wales: a free-standing flagpole is exempt development if it is no higher than 6 metres, no more than 90 mm in diameter and at least 3 metres from each side and rear boundary; only one per lot, and the flag is no larger than 2.5 square metres and not used for advertising.
• Victoria: a pole is exempt from a building permit up to 8 metres above ground, or 3 metres above the highest point of attachment to a building. Under regulation 97, a taller pole needs the report and consent of the council.
• Queensland: accepted development up to 10 metres above the natural ground, or 3.5 metres above a building, outside areas covered by aerodrome standards.
• Western Australia: no building permit up to 3 metres, or 2 metres above the attachment to a building, outside wind regions C and D.
• South Australia: excluded from the definition of development up to 10 metres, or 4 metres above the attachment, except at a local heritage place.
• Tasmania: low risk work up to 6 metres, which an owner, a competent person or a licensed builder may carry out.
• Australian Capital Territory: exempt from development approval up to 10 metres above finished ground level.
• Northern Territory: no building permit up to 6 metres, or 2 metres above the attachment to a building.

A comparison table is in the guide to flagpole heights. Local planning schemes, heritage overlays and bushfire or flood areas can add requirements, which the council can explain.

Building standards still apply

An exemption from a permit is not an exemption from the building rules. In New South Wales, exempt development has to meet the relevant deemed-to-satisfy provisions of the Building Code of Australia or, where there are none, be structurally adequate; it must be installed in accordance with the manufacturer’s specifications; and it may not be carried out on land with an item on the State Heritage Register. In Victoria, the Department of Education points out that under the National Construction Code a flagpole has to perform adequately under all reasonably expected design actions and avoid causing damage to other properties.

The footing

According to the Victorian Department of Education, a free-standing flagpole can be installed in three ways:

• a fixed base, with a concrete base poured around the pole or a tubular sleeve into which the pole is inserted, or a base plate bolted to a concrete footing
• a hinged base, where the footing carries a metal hinge so that the pole can be lowered for maintenance
• attached to a building, for sites without room for an in-ground pole.

The manufacturer usually sets the size of the footing according to the pole’s height, the flag size, the soil and the local wind region.

Underground services

Footings can hit cables and pipes. Before You Dig Australia (BYDA) provides a free service for requesting plans of underground utilities, online and through an app, and according to BYDA any project, including work on private property, can damage assets and lead to injury or death. The Victorian guidance for schools adds that footings can disturb underground water or electricity assets, that contaminated soil, including asbestos, may be found, and that consent may be needed to build near or over an easement.

Overhead power lines

A flagpole that is lifted into place, lowered on a hinge or falls in a storm can reach power lines. BYDA’s Look Up and Live tool shows overhead power lines and safe approach distances. In Victoria, the Department of Education notes that the Electricity Safety (General) Regulations 2019 set minimum distances to aerial lines and suggests consulting the electricity supplier when a pole is to be built near overhead power lines.

Choosing the site

The Victorian guidance recommends the entrance of a school campus, or places where the community gathers, as locations for school flagpoles. For any site, the practical questions are similar: the distance to boundaries and buildings, room for the pole to be lowered if it is hinged, access for delivery and a crane for tall poles, and whether a light at night would shine into neighbours’ windows. Lighting near the Siding Spring Observatory in New South Wales needs an assessment, as described in the guide to flag lighting.

Who installs the pole

Small poles are often installed by their owners. For Victorian government schools, the Department of Education asks for a building professional experienced in flagpoles, recommends a registered builder and certification by a structural engineer, and requires the installer to hold public liability insurance. Safety during installation is covered in the guide to flagpole safety, and moving a long pole in the guide to transporting a flagpole.
