The construction boom that rocked Australia after World War II created a new face of the country. The cities were developing extra skyscrapers, increasing suburbs, and better infrastructure. But, behind the modernisation, there was a small and dark secret.
Asbestos has been exploited in construction because it has fire-resistant attributes, its strength, and a low cost of mining. But it is now an infamous name that causes life-threatening conditions to health.
This blog explores the three most important asbestos types in Australia that are used in construction, and how it was used along with the legacy they have left.
A Short History of Australian Asbestos
Australia ranked among the top per capita consumers of asbestos in the world. Asbestos existed in homes, businesses, and manufacturing plants between the 1940s and 1980s. It was inexpensive, long-lasting, insulated, and, worst of all, lethal.
Asbestos was mined in Australia, especially since the early 1900s, and more so during and after WWII. The hazard of asbestos exposure was not recognised till the late 80s and the early 90s. Use of all types of asbestos was prohibited in Australia by the year 2003.
But the legacies persist in homes, schools, hospitals, and workplaces constructed during that boom. More awareness of the varieties of asbestos used in construction is paramount.
The Three Main Types of Asbestos Used in Australia
Australia used three forms of asbestos, chrysotile, amosite, and crocidolite in the construction sector during the mid-1900s. All of them have varied properties and uses, yet all are lethal to human health.
Chrysotile (White Asbestos)
It is chrysotile that was prevalent in use in Australia. Its elastic, minute filament structure rendered it a material suitable for roofing, ceilings, walls, and insulation. It is less harmful in comparison with other forms. But it still causes such dangerous diseases as asbestosis and mesothelioma.
Amosite (Brown Asbestos)
Amosite was valued due to its resistance to and strength against heat. It was applied in insulation boards, cement sheets, and ceiling tiles. It has short fibres that are broken, thus even more prone to going airborne during disruptions, raising health hazards.
Crocidolite (Blue Asbestos)
Crocidolite was the most deadly form of asbestos applied in high-pressure insulation and sprays. It’s very fine, sharp fibres go deep into the lung tissue and are associated with
mesothelioma. Also, it often remains even after exposure for only a short time.
Becoming familiar with the forms of asbestos Australia used in the past is essential in identifying possible dangers, especially in older buildings, and safe handling and removal.
Why Awareness Matters: Asbestos in 2025 and Beyond?
The Threat Is Still Out There
Although Australia banned asbestos nationwide in 2003, there are millions of buildings containing asbestos materials that were built before 1990. It is possible that asbestos can be dormant for many years. But when it is disturbed during renovations or demolitions, fibrous materials are released into the air. This risk is not only in the past, but it is an issue today.
Long Delay of the Asbestos Diseases
The long latency of asbestos is one of the most threatening things about its exposure. Mesothelioma, lung cancer, and asbestosis may develop up to 20 to 40 years after the initial exposure to the disease. It implies that people who were exposed in the 1980s may be beginning to show symptoms. Those exposed today may not experience them until decades later.
Danger to Homeowners, Tradies, and DIYers
By 2025, homeowners and property investors who restore old buildings will be more than ever before. Few people realise that asbestos could be hidden, lurking in the eaves, ceilings, fences, floors, or even a splashback. Lacking training in safety or protective equipment, tradies (investors), DIYers, and residents can expose themselves and others.
The Relevance of Continued Learning
Improved knowledge will help to avoid the possibility of an inadvertent exposure. Schools, workplaces, and construction training programmes should also provide education to the population about the types of asbestos in Australia. It uses the challenges they face in identifying hazards.
A safer future begins with awareness.
Knowing the history of the usage of chrysotile, amosite, and crocidolite, Australians will be able to take an active stance in controlling risk. One should be aware of hazards and consult professionals when buying an older home or getting it remodelled.
Final Words
The boom in construction in Australia has created modern-day Australia, yet a silent killer lurks in the asbestos. We need to know that there are different types of asbestos: chrysotile, amosite, and crocidolite. So we can be responsible in our management of this legacy.
When renovating, if you are purchasing or caring about the older material used, always be on the safe side. Asbestos Victoria is there all the way to guide you with trusted advice and professional help.
