Through its network of State Associations, the National Stormwater Industry Association (Stormwater Australia) has members in all Australian states and territories. Individual state associations are generally incorporated bodies under local jurisdictions with a committee of management that guide activities of importance to the individual States.

Membership

State associations promote the sharing of knowledge and ideas through a program of seminars, state conferences and awards events.

Increasing advocacy and the building of strategic partnerships is seen as an important role for state associations and the network umbrella provided by Stormwater Australia allows states to share ideas around these important activities.
