As you can see I have one hundred and one thriving examples of why Queenslanders should doubt your publication’s authenticity.
My home, ‘Bellis’, Brisbane’s sustainable house & garden, has been regularly reported on in local media, including ‘The Courier Mail’, ‘Sunday Mail’, various Quest newspapers, ‘Subtropical Horticulture’ magazine, as well as other publications including the ‘The Sydney Morning Herald’. My garden regularly appears on national television through which I have been sharing information on the culture of ornamental and productive plants using recycled waste water for almost ﬁve
Our household of three have been growing 70% of our fresh food for nearly ﬁve years. The food garden covers 300 square metres of the 800 sq metre property, and the whole garden uses 350 litres of waste water a day. The household hasn’t
used a single litre of mains water for the past six months.
As a national sustainable gardening expert, curator, broadcaster and executive member of Queensland Conservation, our state’s peak conservation organisation, I think the authors who wrote this publication need a fresh perspective before they seek to influence the general gardening public.
Feel free to see the garden for yourself as it opens as part of the Australian Open Garden Scheme on 17 – 18th May 2008. See how simple, safe and effective it is to garden with waster water and grey water.

Minister for Natural Resources and Water and Minister Assisting the Premier in North Queensland
The Honourable Craig Wallace, 26/04/2008
“GREYWATER GUIDE GIVES GREEN TIPS FOR QUEENSLAND GARDENERS
Natural Resources and Water Minister Craig Wallace today released a new guide to help Queensland gardeners use greywater.
The guide gives dos and don’ts for using greywater, lists plants that tolerate greywater and those that don’t and information about maintaining soil quality.
Mr Wallace said the average Australian generated 95 litres of greywater each day, making greywater a good option for keeping gardens and lawns green, especially when water restrictions apply.
“Queensland is a state of keen gardeners – we have more than our share of good green thumbs,” Mr Wallace said.
“Good gardeners know the importance of water and greywater is a great way to save this precious resource – but it must be used responsibly,” he said.
“Using greywater is important because it saves our precious mains water, especially in times of drought.”
Waterwise Queensland: Gardening with greywater is produced by the Department of Natural Resources and Water.
There are two types of greywater – untreated and treated. Untreated grey water is the water direct from showers, the bathroom wash basins and the laundry. However, if the home owner has a grey water treatment system professionally installed on site, this water can be treated and has a greater range of uses.
Important facts contained in the guide are:
· Untreated grey water can only be used on lawns and gardens.
· Treated grey water can be used on lawns, gardens, washing walls, footpaths and vehicles, along with toilet flushing and even recycled back to the laundry.
· Common Queensland garden plants that tolerate greywater are: gardenia, Bird of Paradise, melaleuca, dietes, callistemon, conifers and hibiscus.
· Common plants that are not tolerant of greywater are: grevillea, bougainvillea, camellias, lavender, herbs, ferns, citrus, azaleas and vegetables seedlings.
The guide also has information about turf species that are tolerant of greywater and species that are not.
Mr Wallace said the State Government is offering a rebate of up to $500 for greywater systems.
“So I encourage home owners to consider installing these water-saving products,” he said.
