Treeby is the City of Cockburn’s newest suburb and is located in the northern part of Banjup. Development in Treeby is guided by Development Area 37, which is part of the City’s Town Planning Scheme No. 3. The City is seeking to extend this area through Scheme Amendment 117, to support the recent urbanisation of land adjacent to the original site.

About Treeby

In September 2016, the Geographic Names Committee approved the renaming of a portion of Banjup  to Treeby. The suburb is bound by Armadale Road, Solomon Road, Jandakot Road and Fraser Road. Treeby will consist of residential development and supporting landuses, and includes the recently established Calleya Estate.

Development Area 37

Development Area 37 (DA37) is part of the Town Planning Scheme No. 3 and is the land covered by the Calleya estate and an adjacent lot to the west. DA37 requires structure planning to be undertaken for the land in this area before subdivision and development occurs.

The City has proposed a further Scheme Amendment 117, to accommodate the urbanisation of the landholding to the east, which will extend the DA37 area.

Scheme Amendment 117

The City recently undertook consultation for Lot 1 Ghostgum Avenue, Treeby as part of Scheme Amendment 117.

The proposed amendments involve:
  • Including a portion of Lot 1 Ghostgum Avenue and a portion of Ghostgum Avenue, Banjup, as shown on the Proposed Zoning Plan within the Development Zone
  • Including a portion of Lot 1 Ghostgum Avenue and a portion of Ghostgum Avenue, Banjup, as shown on the Proposed Zoning Plan, within the boundaries of Development Area No. 37
  • Removing a portion of Ghostgum Avenue from Local Reserve Local Road
  • Amending the Scheme map accordingly.
The amendment is required under the Planning and Development Act 2005 to bring the City’s Scheme into line with the recent urbanisation of this land under the Metropolitan Region Scheme.

Calleya Estate

Calleya Estate covers the Stockland-owned section of Treeby. The Calleya Estate Structure Plan outlines the proposed framework and form of residential development, community and educational facilities, pedestrian connections and land uses in this area.
