What should I check in my property contract, and what are the key dates I need to track in New South Wales?

Agent acknowledgement: NSW contracts typically require confirming you were introduced to the property only by the vendor's agent named on the contract — breaching this may mean paying another agent's commission and legal costs. GST: the purchase price is GST-inclusive unless stated otherwise. GST Residential Withholding: if buying new residential property, you generally withhold ~1/11th (or 7% under the margin scheme) and pay it to the ATO; the vendor's legal rep must state in the contract whether this applies. Foreign Resident CGT Withholding: for contracts signed from 1 January 2025 you must withhold 15% of the purchase price — with no minimum price threshold — and pay it to the ATO at settlement, unless the vendor produces a valid ATO clearance certificate or variation notice. Key dates: Contract Date (when signed counterparts are exchanged), Deposit Due (by exchange, or per cooling-off arrangement: 0.25% by exchange + balance by cooling-off expiry), Settlement Date.
