The use of lead paint in Australia was phased out from 1970 onwards, but it was not banned entirely until the early 1990s. In 1991, the Australian NHMRC limited lead content in paint to 0.5% for domestic use, which was lowered to 0.25% in 1992 and further to 0.1% in 1997. Even in small amounts, lead paint is a health hazard, and exposure to it can cause serious long-term health issues.

What You'll Learn
Lead was phased out from 1970 onwards
The use of lead in paint has been a concern in Australia since the late 19th century when two Australian physicians, Gibson and Turner, first described paediatric plumbism. In 1904, J. Gibson published an article in the Australian Medical Gazette linking child lead poisoning to lead-based paints. However, it wasn't until the 1970s that lead was significantly phased out from paint in Australia.
In 1969, national legislation was introduced to restrict lead content in paint, and from 1970 onwards, lead content was reduced to below 1%. This was a significant reduction from the 50% lead content commonly found in paint before 1965. Despite this, lead paint continued to be used in many Australian houses before 1970, and it is recommended to test for lead in buildings painted before the mid-1970s.
The harmful effects of lead exposure were further highlighted in 1971 when the CDC lowered the limit for lead poisoning in children to 40 micrograms/decilitre, and again in 1975 when the limit was lowered to 30 micrograms/decilitre. In 1978, the WHO recommended a tolerable dietary intake of lead, and in 1979, the New England Journal of Medicine described the association between lead exposure and neuropsychological deficits in children.
In the 1990s, Australia took further steps to reduce lead content in paint. In 1991, the Australian NHMRC limit for lead in paint was lowered to 0.5% for domestic use, and in 1992, it was reduced to 0.25%. Finally, in 1997, the limit was lowered to 0.1%, bringing lead content in paint to much lower levels than in previous decades.
Today, lead paint is considered a health hazard, particularly when it is disturbed through activities such as home renovations or maintenance. It is important to take precautions when working with lead paint, such as using protective clothing and respirators, and ensuring that children, pregnant women, and pets are not exposed to lead residues.

National legislation to restrict lead content introduced in 1969
In 1904, an Australian Medical Gazette article by J. Gibson linked child lead poisoning to lead-based paints. Despite this discovery, paint containing significant quantities of lead was manufactured in most Australian states until the late 1960s. In 1922, Queensland banned the use of lead in paint, and other states began to reduce its presence from 1950.
In 1969, national legislation was introduced to restrict lead content in paint. From 1970 onwards, lead content was reduced to below 1%. However, this legislation did not entirely prohibit the use of lead in paint. In 1991, the Australian NHMRC limit for lead in paint was 0.5% for domestic use. This figure was lowered to 0.25% in March 1992 and further reduced to 0.1% in 1997.
It is important to note that lead in house paint is only a problem if it is damaged or disturbed. Paint in good condition that is not flaking or chalking is not a hazard in itself. However, lead can be hazardous when it is on surfaces subject to friction or impact, such as windows and doors, or on railings where children can chew it.
When renovating or doing maintenance that could disturb old paint, it is crucial to take precautions to avoid exposing yourself, your family, your neighbours, and your pets to lead residues. This includes wearing protective clothing, respirators, and following recommended guidelines for paint removal.
While lead was phased out from 1970 onwards, it is still important to test for lead paint in buildings constructed before the mid-1970s to ensure the safety of occupants and workers involved in renovation or maintenance projects.

The Australian NHMRC limited lead in paint to 0.5% in 1991
The harmful effects of lead paint were first discovered in the 1930s by a doctor in Queensland, Australia. Despite this, paint containing significant quantities of lead was manufactured in most Australian states until the late 1960s. In 1969, national legislation was introduced to restrict lead content. From 1970 onwards, lead content was reduced to below 1%.
In 1991, the Australian NHMRC limited lead in paint to 0.5% for domestic use. This limit was lowered to 0.25% in March 1992 and further reduced to 0.1% in 1997.
The Australian NHMRC's decision to limit lead in paint to 0.5% in 1991 was a significant step in the right direction for the country. While it did not entirely prohibit the use of lead in paint, it represented a substantial reduction from previous years. For context, the recommended amount of lead in domestic paint was 50% before 1965, which decreased to 1% in 1965.
The 1991 limit was part of a gradual phase-out process that began in the 1970s. During this time, lead paint was recognised as a health hazard, and its use was gradually reduced and regulated. By the early 1990s, lead paint was largely prohibited in Australia, with the remaining lead content being limited to trace amounts for domestic use.
The phase-out process was not immediate, and it took several years for the limits to be lowered to the point where lead paint was essentially banned. This gradual approach allowed for a transition period, during which manufacturers could adjust their formulas and processes to comply with the new regulations.

Lead content in paint was reduced to 0.1% in 1997
In 1997, Australia reduced the maximum permissible lead content in paint to 0.1%. This was a significant milestone in the country's efforts to mitigate the harmful effects of lead exposure, which had been recognised since the late 19th century.
The dangers of lead-based paint were first described by Australian physicians Gibson and Turner at the end of the 19th century, in what was termed "paediatric plumbism". However, it was not until the 1930s that the link between lead paint and health issues was conclusively established by a doctor in Queensland. Despite this knowledge, paint containing significant amounts of lead continued to be manufactured in most Australian states until the late 1960s.
In 1969, national legislation was introduced to restrict lead content in paint, and from 1970 onwards, lead content was reduced to below 1%. This was a substantial decrease from the 50% lead content found in paints before 1965. However, it was not until 1991 that the Australian NHMRC set a limit of 0.5% for lead in domestic paint. This limit was subsequently lowered to 0.25% in 1992, and then to 0.1% in 1997.
The reduction of lead content in paint to 0.1% in 1997 marked a significant step towards protecting public health and reducing the risks associated with lead exposure. Lead can cause serious long-term health issues and harm almost every part of the human body, including the brain, kidneys, and reproductive organs. Children under four, pregnant women, and their foetuses are particularly vulnerable to the harmful effects of lead exposure.

Leaded petrol was banned in 2002
The use of lead in paint and petrol has been a concern in Australia since the early 20th century. In 1904, a link between child lead poisoning and lead-based paints was established by J. Gibson in the Australian Medical Gazette. Despite this, lead was only limited to 0.1% in Australian house paint in 1992, with further reductions to 0.25% in 1997.
In 1994, a UN commission called on governments worldwide to switch from leaded to unleaded petrol. Following this, Australia phased out leaded petrol in 2002, with the exception of Avgas, which is still permitted for water sports and motor racing.
The dangers of lead exposure are well-documented, with lead poisoning causing severe health issues such as brain damage or even death. Lead was a common ingredient in paints until the 1980s in Australia and was not entirely prohibited until the early 1990s.
Due to the health risks associated with lead exposure, it is crucial to test for lead paint in buildings, especially those constructed before the mid-1970s, and to implement safety measures during renovation or maintenance work. Lead test kits are readily available and can help identify potential hazards.

Frequently asked questions
Lead paint was phased out in Australia from 1970 onwards, but it was not entirely prohibited until the early 1990s.
If there are concerns about potential lead exposure, it is recommended to get a blood test from a GP. If lead paint is confirmed, professional testing can determine the best course of action, such as complete removal or encapsulation to seal the lead. Safety precautions must be followed to minimise exposure to individuals and their families.
Lead paint is particularly hazardous when disturbed, as it can release lead dust and paint chips that can be inhaled or ingested. Lead exposure can cause severe health issues, including brain damage and, in extreme cases, death.
Lead paint removal should be handled by licensed professionals to ensure safety. Recommended precautions include covering or removing the paint using techniques such as wet scraping, wet sanding, chemical stripping, or heat processes. Protective clothing and respirators are also essential when working with lead-bearing materials.
In Australia, it is advised to test for lead paint in buildings painted before the mid-1970s. Lead test kits are available at hardware stores or paint shops, and multiple layers of paint should be tested. Testing is crucial to ensure the safety of occupants and workers during renovation or maintenance projects.
