the period of validity of a registered Australian trademark is 1 years from the date of application. You can apply for renewal within one year before the expiration of each registration period, and the validity period after renewal is also 1 years, and you can renew it once every 1 years. You don't need to submit any use evidence for renewal application, just pay the fee. If it is not renewed within the time limit, it can also apply for renewal within a 12-month grace period from the expiry date of registration, but it must pay a fine. However, after five years of trademark registration, if the trademark has not been used for five consecutive years, any interested party may apply to the Trademark Office for cancellation of the trademark registration.
