Revesby and Condell Park odours

We are aware that the community experiences odours around Revesby and Condell Park from time to time with characteristics described as rubber, burning, gas and chemical.

We appreciate that odours can be subjective, unpleasant and can impact quality of life.

The EPA reviews each report of odour from the community and works to investigate potential sources of odours, such as by conducting odour surveys in the Revesby and Condell Park areas. Odour surveys are undertaken when meteorological conditions are likely to increase odour impact and during the times that odours are mostly commonly reported in this area.

There are several facilities in the area that may be contributing to offensive odours. We work to ensure odours are appropriately managed. We will take appropriate regulatory action when required.

What you can do

Community reports help us understand which odours occur when and where, providing key information about odours that may affect the community.

If future odours occur, please provide the following details in a report to the EPA:

• the location where you experienced the odour
• the time you first noticed the odour
• how long the odour lasted
• what the odour smelled like.

If you are experiencing offensive odour, please email [email protected]. Information about persistent odour can also be recorded using the fact sheet and odour log sheet, which can then be emailed to us.

If you believe the odour originates from an EPA regulated premises (see the EPA POEO Public register) we also encourage you to report it directly through the premises complaints and enquiries line. This helps them investigate potential odour sources in real time.

Hydrogen sulphide monitors in the community

We have installed 5 electronic monitors in the local area to detect hydrogen sulphide, a colourless gas that smells like rotten eggs, and can be a component in other odours. Hydrogen sulphide odours can come from natural sources, including creeks and estuaries, as well as from industrial activities.

These monitors:

• are small (about the size of a litre carton of milk) and automatic.
• take an air sample every 10 minutes and analyse it for hydrogen sulphide, detecting levels as low as 3 parts per billion (ppb).
• help us combine community reports, EPA surveys, and monitor data to pinpoint odour sources.

Hydrogen sulphide detections to date have been at very low concentrations unlikely to affect human health.

The data collected will be updated weekly.

Odours and health

NSW Health advises people can smell hydrogen sulphide at very low levels. Most people notice it at around 8 ppb, but some people can smell it at levels as low as 0.5 ppb. 

Exposure to hydrogen sulphide concentrations of 5,000–30,000 ppb may cause irritation of the eyes, nose, or throat, and difficulty breathing in people with asthma. Repeated exposures at these levels can cause anxiety and distress and result in indirect symptoms such as headaches and nausea. 

These effects are usually mild and temporary. Hydrogen sulphide does not accumulate in the body, and symptoms generally resolve once the air clears. If residents are concerned about their symptoms or if symptoms persist once the odours have ceased, they should seek advice from their doctor.

Hydrogen sulphide levels

The interactive charts show levels of hydrogen sulphide detected at 5 monitors deployed in the local area. These monitors were installed In June 2026. To explore the data obtained since their installation date, use the slider at the bottom of each chart.
