Stimulating Sustainability Nationally


Along with the Australian Greens, you may have preferred the Federal Government's recent economic stimulus package to have been spent on infrastructure projects and initiatives that support sustainability and mitigate climate change, rather than cash payments designed to encourage shopping sprees.

The Government has chosen to give people earning under $80,000 a one-off payment of $900*. However you can still choose to use this money to address climate change by increasing your home energy efficiency and minimising water use. Doing this may even save you money in the long run!

Below are just some of the water and energy efficiency products that Australian residents can buy for $900 or less, including rebates from the State and Federal governments. There may also some rebates available from your local council. (These have not been included, so ask your local council about what they offer.)
* Smaller payments are also being made to people earning under $100,000. Information on eligibility and timing for payments is available on the ATO website.
