Quick answer
Confined space work in Australia is governed by the model Work Health and Safety Regulations and the Safe Work Australia Confined spaces Code of Practice (adopted by most states and territories). In short: identify confined spaces, eliminate the need to enter where possible, and if entry is required, use a written entry permit, atmospheric testing, trained workers, a standby person, and a rescue plan.
The core duties
- Identify confined spaces and assess the risks
- Eliminate or minimise — avoid entry if the work can be done another way
- Entry permit — authorise entry in writing with the controls listed
- Atmospheric testing — before and during entry
- Trained workers + standby person — competent people, with someone outside
- Emergency plan — workable rescue that doesn’t rely on entering unprotected
Training is a legal expectation
Workers who enter confined spaces, issue permits, or act as standby must be trained and competent. The nationally recognised unit is RIIWHS202E Enter and Work in Confined Spaces. See the Confined Space course →
State differences
Most jurisdictions follow the model WHS laws, but the Code of Practice must be adopted in your state to have legal effect, and Victoria runs a separate scheme. Check your WHS regulator for the version that applies to you.
Frequently asked questions
Is a confined space entry permit legally required?
Yes — under the WHS Regulations, entry to a confined space must be authorised by a written permit with the required controls.
Do confined space rules vary by state?
Most states use the model WHS laws, but adoption and some details vary. Confirm with your local regulator.
Does the law require training?
Workers must be competent; nationally recognised RIIWHS202E training is the standard way to demonstrate that.
