[Greg Priest]: Perth Zoo's been open since 1898. We have 700,000 plus visitors a year coming through our gates.

We have 1,500 plus animals across site. It means that we're big water user. So we work very hard to reduce our water footprint across the zoo.

We participate in the Water Corporation's Waterwise Business Program and have been an original partner since 2005.

It's been such an important partnership to work with Water Corporation. And each year, we conduct and complete our Water Efficiency Management Plan, which is an amazing tool to make sure we put in place goals, objectives and targets for water efficiency and manage how our water is used across site.

Perth Zoo has rolled out a number of water efficiency activities over the last 15-20 years, beginning with the replacement of our water fittings in bathrooms and toilets. We've put in place a minimum three star WELS water efficiency rating.

Finding leaks and bursts and replacing those. Installing a smart irrigation system, hydrozoning, as well as upgrading a number of other exhibits and facilities to recycle water that was consumed in our Western Swamp Tortoise breeding program ponds, to reuse that water down through our Australian wetland and then through our main lake.

[Alan Gill]: Water forms a really important part of habitat for a vast number of wild animals, particularly here in Western Australia for critically endangered species, like the Western Swamp Tortoise.

Saving water and our water resources plays a really key role in saving these species.

Most of our visitors come to the zoo because of the animals, but our animals wouldn't exist if it weren't for the planet that we live on, and water is a really key part of the ecosystem that they inhabit.

It's important that we understand what climate change is doing to our habitats, the impact that it has on wildlife, as well as the impact that it has on our water resources.

[Greg Priest]: As a large water user, it's very important to reduce our water footprint, to make sure that there's sufficient water out in the natural environment to care for the animals and make sure there's water for the future of Western Australia.
