Engineering Technologists on the National Engineering Technologists Register (NETR) are normally registered in at least one general area of practice, in which they satisfy the Australian Engineering Competency Standards Stage 2 - Engineering Technologist. Engineering Technologists may also be listed in a specific area of practice if it is essential to their practice.
Information on the general areas of practice on NETR gives a reasonable indication of services likely to be delivered by registered Engineering Technologists.

The number of general areas of practice was limited originally to one. This has been increased to twelve areas of practice, which will remain limited to avoid excessive overlap between them. The scope of practice within each general area is defined by the Attributes of an Engineering Technologist.
All registered engineering practitioners observe a common Code of Ethics, undertake to accept responsibility for outcomes only within their area of competence and specifically commit to keeping up-to-date through continuing professional development to support their engagement in delivering engineering services. They deliver engineering outcomes that minimise adverse social, economic and environmental consequences, with due regard for the safety, health and welfare of the community.
The National Engineering Registration Board ensures that the broader community, in whose interests NETR has been established, is effectively represented in deciding how the register will be run.
In response to government and industry demand, five much more specific areas of practice have been made available to practitioners registered in one of the general areas of practice on NETR. Information on the specific areas of practice on NETR also gives a reasonable indication of services likely to be delivered by registered engineering technologists.
