Our unique heritage treasure

The rock engravings or petroglyphs of Murujuga (Burrup Peninsula), Western Australia form the largest collection of rock art in the world. 50,000 years of Australian history and complex art production is preserved, including some of the world’s oldest known images of the human face. More than one million engravings depict extinct fauna such as Tasmanian tigers and fat-tailed kangaroos, changes in bird and marine species over time, as well as ancient Indigenous beliefs and rituals. This extraordinary art is an irreplaceable part of Australia’s heritage that is globally significant.

Our problem

Governments have encouraged industrial development immediately adjacent to the rock art, including:

  • an iron ore export terminal and a salt production/export facility (1960s)
  • natural gas processing facilities and two large liquefied natural gas plants (1980s – 2000s)
  • an ammonium fertiliser plant (began production in 2006)
  • an ammonium nitrate explosives production facility is currently being commissioned

In spite of this development, more than 85% of Murujuga rock art survives. It is formally recognised and protected on Australia’s National Heritage List and cared for by sensitive local Indigenous managers. However, the rock engravings are now threatened by pollution without adequate monitoring in place. Local industry emits at least 34,000 tonnes of acidic compounds into the air each year. These mix with moisture and produce acid rain that dissolves the rock surface. The severity of the pollution is greater than in many international cities. The daily red-brown haze over the area appears as rainfall on Bureau of Meteorology radar, even though the skies are usually cloudless. Why? The pollution is so bad that the radar ‘sees’ it as rain.

Acid rain is a threat to rock art and human health


A huge yellow cloud of nitrogen dioxide was released in April 2017 and, as revealed in Parliament, it had a concentration of 2088 parts per million (ppm). This is an extremely high concentration since >2 ppm is dangerous to human health. Similar emissions will occur up to six times a year – whenever the ammonium nitrate plant is restarted after maintenance. Local residents and workers could be at risk.

Preliminary measurements of acidity by our team indicate that rock surfaces may have reached an acidity level sufficient to dissolve the rock coating. Both the rock art and environment are threatened. We need to act NOW!


Not enough is being done to understand the threats

During the last decade there has been:

  • No published air pollution data for Murujuga
  • No testing of groundwater pollution even though Indigenous elders have complained that local water is ‘poisoned’
  • No measurement of microbiological growth on rock surfaces, even though the fertilizing effects of pollutants cause rapid increases in lichens that damage rock art
  • No testing of the pollutants’ effects on vegetation, even though a rapid increase in fuel load can lead to more intensive burns and extensive damage to rock art
  • No current comprehensive monitoring of the rock art’s condition

The lack of regard for the effects of pollution on Murujuga’s rock art is unacceptable. Similarly important cultural heritage sites, such as Lascaux Cave in France and Stonehenge in UK, are monitored constantly for decay and protected by long-term conservation strategies. It is extraordinary for a site of this importance to lack effective protection from decay. The situation is so alarming that a Senate Inquiry was set up to investigate the matter in December 2016 and will release its findings soon.


Our solution

With the approval of the Traditional Aboriginal Owners, we have assembled a team of international experts. The team will be led by one of Australia's top universities, the University of Western Australia. They will work in partnership with Traditional Owners, Indigenous Rangers, The Friends of Australian Rock Art (FARA), the Western Australian Museum, the National Trust (WA) and the Conservation Council (WA) to:

  • Measure gaseous and particle emissions in order to evaluate the changes to the rock surfaces and the local environment
  • Measure and monitor changes in colour and mineral composition of rock surfaces at representative sites
  • Measure and monitor changes in air and water acid levels, and their effect on local plant species and the environment
  • Use theory and data to model and predict the effects of different levels of acidic emissions on the rocks and rock art, and develop ways to reduce or eliminate the effects
  • Use new knowledge to persuade governments and industry to reduce emissions to safe levels

This project is essential to the survival of Murujuga rock art


Your donation is vital

We have to raise $250,000/year for five years. Data over successive years are needed to document changes over time.

The $100,000 raised in this campaign will be added to funds committed by philanthropists, Indigenous organisations, conservation organisations and concerned individuals, and will enable us to apply for matching government funds through an Australian Research Council Linkage Grant.

Please support us. Your contribution matters. All donations to this campaign are tax deductable.
