You generally must pay transfer duty when you buy a property or ownership is transferred to you in NSW. Revenue NSW lists exemptions and concessions separately.

Queensland
Transfer duty, formerly known as stamp duty, is charged by the Queensland Government on transactions such as buying property, land or dutiable assets.

Transfer duty applies to transfers of real estate and certain business assets. Liability usually arises on the date the document is signed, and the person liable is generally the purchaser.

Duty is charged under the Duties Act 2001 when you acquire an interest in dutiable property. It is payable within three months of the transaction, usually settlement, by the purchaser.
South Australia, ACT and Northern Territory
Their revenue offices did not let us read their pages when we checked, so we quote nothing for them here.
