Arguments against development on Area A put
forward by PPG
1. Selections from Fact Sheet on Creery Wetlands presented to Mandurah City councillors
and other interested parties in 1998.
Facts
......2. Evidence is mounting world wide on the destructive nature of
canal estates and last year the New South Wales Government directed their local Councils
to enforce a new policy to ban any more canal estates on environmental grounds.
3. Figures on the costs to local Councils of maintaining canal estates are mounting every year.
These costs include maintaining canal walling and water quality.
4. In a letter to the W A Minister for the Environment August 1993 the Australian Nature Conservation
Agency, ANCA, stated This agency believes that the recommendations of the EPA and the responses
by the proponent are inadequate and fundamentally flawed in that they fail to address the environmental issues
at stake. Also The only outcome will be the loss of valuable habitat for the many species which
utilise the area, and the potential for further impact on the water quality for the Ramsar listed areas of
the Peel-Harvey Estuary.
5. In the EPA bulletin 695 1993, on the Harbour Canal Estate for the Creery Wetlands, a time limit of 5 years
for commencement of the project was recommended, after which a reassessment must be made. This time limit
expires in August 1998.
6. The advice given in the EPA Bulletin 695, that the Harbour City Canal Development could go ahead under
certain strict environmental conditions, was based upon an Environmental Review commissioned by the proponent
This Environmental Review has been strongly criticised in peer review documents released last year under the
Freedom of Information Act. These documents claim that, not only was the Environmental Review factually
incorrect in some of its data but it also drew faulty conclusions from it. We suggest that, should the EPA
reassess the development in the light of this criticism, and of mounting scientific evidence on the value of
wetlands and remnant native vegetation, they would be most likely to recommend against the development.
7. In September 1994 a Mandurah referendum overwhelmingly rejected the proposed Harbour City canal estate on the
Creery Wetlands. This led directly to Mandurah councillors rejecting a rezoning proposal for the Wetlands.
There is no reason to believe that Mandurah residents have changed their minds.
Scientific data is accumulating steadily on the environmental value of Area A
of the Creery Wetlands.
8. City of Mandurah State of the Environment Report 1997 p34 states:
There are a number of important wetlands in the City of Mandurah.
The Creery Wetlands are a good example, having a high level of biodiversity with large trees, intact
understory and samphire flats.
9. An opinion on the value of the Creery Wetlands expressed in 1995 to ANCA by Dr Semeniuk of WA, states:
Preservation of the geomorphic values of a wetland requires that the boundary of said wetland be
kept intact and that its context, in this case its relationship with surrounding hinterland and the estuarine
water body, be retained.
10. Experts from the Wildflower Society of WA gave this opinion in Jan. 1998: A large portion of Area A
is considered part of the wetland unit and should be preserved as such. These scientists are continuing
their study of the Creery Wetlands using aerial photos supplied by PPG - more information from them is expected soon.
11. A member of the Dept. of Environmental Protection has stated that freshwater seepage
into estuaries and inlets produced unique ecosystems and every effort should be made to conserve them.
One such freshwater seepage (see Picture) occurs on Area A of the Creery Wetland,
12. PPG have identified 26 species of local native plants including large Jarrah and Tuart trees on Area A
of the Creery Wetlands. Tuarts are under threat throughout the State due to heavy development along the coastal
strip. The City of Mandurah's State of the Environment Report 1997 states on P34 In remnant Jarrah and
Tuart forests, fauna is well represented by the Grey Kangaroo, Emu, Brush Wallaby, Short-nosed Bandicoot
and diverse bird populations. This includes two rarely sighted bird species: the Peregrine Falcon and Red-eared
Firetail Finch.
Conclusions
In the light of mounting scientific evidence on the value of wetlands and remnant native vegetation,and on the
environmentally destructive effect of Canal Estates, we suggest any proposal for Canals on Creery should be
reassessed by the EPA. This would be in line with their sunset clause recommendation in Bulletin 695.
(see Fact 5 above).
Until this has been done, rezoning of Area A of the Creery should not go ahead as it may be decided to add
Area A to Conservation Zones B and C.
These arguments (prepared for the PPG committee by Griselda Hitchcock,
Beryl Francis and Sue Grayling) were
presented to Mandurah City Councillors and similar presentations were made to the Ministers
for Planning and also Environment.
