Summary: Tax-free land investment in Sydney in 2025 can be achieved through a Self-Managed Super Fund (SMSF), offering key benefits such as investment autonomy and tax advantages. Setting up an SMSF requires the assistance of an experienced accountant to reduce audit risks and manage funds through a dedicated bank account. Additionally, with recent policy relaxations on land development in Sydney and tax exemption policies, the potential for land appreciation is significant. However, investors should be cautious about areas where property prices have already peaked.
