You can obtain information regarding the zonings and reservations of your property by obtaining a clause 42 (MRS), clause 47 (PRS) or clause 53 (GBRS) certificate.
Each certificate costs AUD$27 and the applicant is required to fill in an application form and supply a photocopy of the Certificate of Title and Strata Plan (if the lot is a strata).
If the lot is affected by a reservation, the certificate will have a sketch showing how much of the lot is reserved. This reservation is depicted on the sketch by the use of dimensions along the cadastral boundaries, enabling the applicant to see how much of the property is affected.
If the lot is not affected by a reservation you will still get a map depicting the land use zoning.
