This document provides guidance on planning and designing a water-efficient garden. It emphasizes choosing plants suited to the local climate and soil conditions, using permeable paving and mulch, and minimizing lawn areas which require a lot of water. Specific design principles discussed include considering the property's sun exposure, slope, views and intended use; understanding microclimates; and matching the garden style to one's lifestyle and home. The overall message is that with proper planning, gardens can thrive on natural rainfall without excessive watering.

by high evapotranspiration rates, which is
the combination of water lost through
evaporation and transpiration from plants.
As a result, there are low amounts of runoff
into streams and rivers (11% of average
rainfall) and low replenishment of
groundwater (1% of average rainfall).
Australia represents approximately 5% of
the world's land area yet we only have 1% of
the global river runoff. We must therefore
be even more careful to use water
sparingly.
