Yes, but you need realistic expectations about what that budget can achieve. In Sydney, $100,000 is unlikely to cover a full whole-house renovation, but it can go a long way on targeted improvements.
You could update a kitchen and one bathroom, replace flooring throughout, repaint inside and out, and refresh fixtures and lighting across most rooms. What you cannot do at this price point is structural work, extensions, or high-end finishes across multiple rooms. Prioritise the spaces that add the most value, generally the kitchen and bathrooms, keep your selections practical rather than premium, and set aside at least 10 to 15 percent as a contingency.
