You will require an offshore retention lease if you intend to become the leaseholder of an offshore area that contains petroleum not commercially viable for extraction purposes at the point of application, but will become commercially viable within 15 years of the application.
A petroleum retention lease may be obtained as a result of a change to the boundary of the coastal waters of a State or Territory.
Please note that you will be required to contact the Agency if there are any identified greenhouse gas storage formations situated in the lease area.
