Water catchments

Drinking water catchments encompass the major portion (around 80% or 4500 sq km) of forested walk areas close to Perth. They cover a large majority of walk areas included on WalkGPS and affect access for bushwalking.

Reservoir Protection Zones (RPZs)

Entry to 2km-wide RPZs around the water reservoirs is currently prohibited as a precautionary measure intended to protect against perceived risks to drinking water quality.

Outer catchments

Traditional backpacking involving overnight stays in the outer catchments beyond the RPZs and away from the Bibbulmun Track has also been banned under Department of Water (DoW) policies since 2003.

DoW plans published in 2007 also in effect intended to bar day bushwalking from the entire outer catchments except along the Bibbulmun Track and other unspecified ‘designated’ tracks. The outer catchments extend far beyond the limits of the RPZs, across most of the northern 4500 sq km of forested area of the region. Such a proposed ban if implemented would have been the death knell for traditional (partly cross-country) bushwalking in the Perth region.

Thanks to extensive submissions to Government by bushwalkers and other community groups, the DoW reconsidered its published 2007 Plans. In a 2012 policy update DoW ultimately refrained from a ban on traditional cross-country bushwalking in the outer catchments.

A future for traditional bushwalking?

DoW’s “Operational Policy 13: Recreation within public drinking water source areas on Crown land” is to be reviewed again in 2018. Existing and aspiring bushwalkers, bushwalking clubs and all others interested in the continuation of traditional bushwalking need to be vigilant. There can be no net cost benefit to the State of lower cost pure, sterile water if it comes at the high cost of a generally unfit and unhealthy community lacking access to sufficient and  enjoyable recreational activities. Bushwalking has long been a popular, healthy and compatible recreational activity in our parks and state forests in the Perth region; It must continue to be recognised as a legitimate activity into the future.
