My Passport has expired can I still travel?

No, you are only allowed to travel abroad using a valid passport.

A valid passport is essential when you travel abroad. Although your passport has been issued for 10 years (5 years for children), some overseas countries have an immigration requirement for a passport to remain valid for a minimum period after the date of entry to that country (typically 6 months).

All countries require that your passport is valid both on the day you arrive and on the day you leave. If your passport is in its final year of validity, you are advised to check the requirements of the country(ies) of destination before you make final travel plans.
