The Federal Government announced measures in June 2020 to give $25,000 grants to substantially renovate and extend existing homes. If you are eligible, it applies to renovations and extensions between now and the end of 2020.
However, don’t worry if you think you will miss out on this grant. The good news is that an extension has been granted to 31 March 2021. The downside is that the grant is reduced to $15,000.
