What year did catalytic converters become mandatory in Australia?

Australia has had road vehicle emission standards for new vehicles in place since the early 1970s and these have been progressively tightened over the past 45 years. Because of that, catalytic converters were found to provide an answer to the control of emissions and to provide compliance with the regulated emissions standards of the day. It appears there is no law that says a cat must be fitted but a passenger vehicle must however comply with the emissions requirements and cats can provide the answer. i.e. there could be something else that could do the job, once discovered.

Normally when catalytic converters become clogged and need replacing there is a reason for this. Something caused the converter to become clogged.
