Flagpole and flag lifespan in Australian conditions

A flagpole and the flag on it age at very different speeds. The pole can stand for decades; the flag, in Australian sun and wind, may last a few months. What decides the lifespan of both is exposure: UV, wind, salt air and how many hours a day the flag flies.

How long a flag lasts

According to the Australian flag maker Evan Evans:

• a quality flag can last around 6 to 12 months with proper care
• flags in strong sun, salt air or constant wind may need replacing closer to 3 months
• a flag left outdoors day and night in harsh conditions can fade or fray quickly, sometimes within weeks
• flags flown at extreme heights or in exposed locations may wear faster because of stronger wind.

The protocol of the Department of the Prime Minister and Cabinet (PM&C) states that the flag should never be flown when it is damaged, faded or dilapidated, so a faded flag reaches the end of its use before it wears through.

What extends a flag’s life

Evan Evans describes several ways to make a flag last longer:

• Daylight only: flags flown during daylight hours only usually last longer, and bringing a flag in at dusk helps preserve colour and stitching. The PM&C protocol also links flying at night to lighting.
• Severe weather: removing the flag during storms and high winds where possible.
• Rotation: using two flags in rotation can significantly extend their usable life, especially where flags fly every day.
• Care: washing gently and letting the flag dry fully before storing it.

A heavier fabric, such as woven polyester, and double stitching at the fly also help in exposed places. More in the guide to buying a flag.

How long a flagpole lasts

The pole itself lasts far longer. According to the Victorian Department of Education, most flagpoles are aluminium with an anodised or powder-coated finish; with its finish intact and its fittings maintained, such a pole can stand for decades. What shortens its life:

• corrosion at the base, where water and salt collect
• damage to the finish, which exposes the metal
• storms and cyclones, which can bend or crack a pole
• loose or cracked footings.

Parts such as the halyard, pulley, clips and finial wear out several times during the life of a pole and are replaced. More in the guides to flagpole maintenance and flagpole repair.

Sustainability

• A longer life: a pole that lasts, with replaceable parts, uses fewer resources than one replaced early. Aluminium can be recycled at the end of its life.
• Fewer flags: flying by day, lowering in storms and rotating two flags reduce how many flags are needed.
• Recycling flags: Evan Evans runs a recycling program for used flags and fabric banners.

Old flags

When a flag is no longer suitable for use, PM&C describes two options: keeping it in a permanent place of storage, or destroying it privately and in a dignified way, for example by cutting it into small unrecognisable pieces, placing them in a sealed bag or closed container and putting it in the normal rubbish collection. PM&C also publishes an outline of an optional flag retirement ceremony. More in the guide to flag flying rules, and a comparison of materials in the guide to flagpole materials.
