Stormwater Charge

[susiejones]

Here's one for the knowledgable:

Excerpt from Local Government Act 1993:
496A Making and levying of annual charges for stormwater management services
(1) A council may, in accordance with the regulations, make and levy an annual charge for the provision of stormwater management services for each parcel of rateable land for which the service is available.
(2) Subsection (1) does not authorise or permit a council to make or levy an annual charge for the provision of stormwater management services for rateable land that is:
(a) owned by the Crown, and
(b) held under a lease for private purposes granted under the Housing Act 2001 or the Aboriginal Housing Act 1998.
Note. Section 555 (1) (a) provides that land owned by the Crown is not rateable land unless it is held under a lease for a private purpose.

Question: How can I find out if an assessment is crown land held under a lease for private purposes granted under the Housing Act 2011 or the Aboriginal Housing Act 1998? - Is it just all housing commission housing and housing owned by Aboriginal Housing Associations?
