Home improvements that add the most value in Australia include kitchen renovations (100–140% ROI), bathroom refits (100–130%), cosmetic paint and flooring (150–200%), outdoor decking (90–120%), and solar systems (75–100%).
Kitchen and bathroom renovations consistently deliver the best ROI, often returning 100–140% of their cost in added value. Cosmetic refreshes (painting, flooring) have the highest ROI per dollar spent, often returning 150–200%.
It varies by location. In QLD and WA, pools consistently add value — often matching installation cost. In Victoria and Tasmania, pools add less value due to shorter swim seasons.
