Highly sensitive details of the negotiations over the little-known Trades in Services Agreement (TiSA) published by WikiLeaks reveals Australia is pushing for extensive international financial deregulation while other proposals could see Australians' personal and financial data freely transferred overseas.

The secret trade documents also show Australia could allow an influx of foreign professional workers and see a sharp wind back in the ability of government to regulate qualifications, licensing and technical standards including in relation to health, environment and transport services.

In its largest disclosure yet relating to the TiSA negotiations, WikiLeaks has published seventeen documents including draft treaty chapters, memoranda and other texts setting out the overall state of negotiations and individual country positions in a secret bargaining on banking and finance, telecommunications and e-commerce, health, as well as maritime and air transport.

The leaked documents were to be kept secret until at least five years after the completion of the TiSA negotiations and entry into force of the trade agreement.
