Are there any Mutual Recognition Agreements in place between Australia and overseas countries?
Mutual recognition with New Zealand applies through the Trans-Tasman Mutual Recognition Agreement. Currently registered architects wishing to become registered in New Zealand under the terms of this agreement should contact the New Zealand Registered Architects Board.
The USA/New Zealand/Australia allows for Australian architects to be registered in 30 US states and territories without completing further examinations. See here for more details.
Australia is a signatory to the APEC Architect Mutual Recognition Agreement. Currently there are mutual recognition agreements in place with Japan, Singapore and Canada.
