ok just googled it for ya, i dont know if this will help but....

A restrictive covenant is a private agreement between land owners which may restrict the way land may be used and developed. A covenant is not administered or enforced by the government or a municipal council
How can a covenant be removed or varied?
A covenant can be removed or varied:


If authorised by a permit under the Planning and Environment1987
If authorised by a provision of a planning scheme or an amendment to a planning scheme under the Planning and Environment Act 1987

Any person proposing to seek variation or removal of a covenant under any of these procedures should obtain their own expert legal advice about options and procedures appropriate to the particular circumstances of the case, before making any commitments or starting any procedures. Likely costs, which may be substantial, should be taken into account before any action is started.
