Australian Defence Vessel (ADV) Guidance is an undersea support vessel. The ship operates under the Royal Australian Naval Flag (Blue Ensign) with a contracted civilian crew from Teekay Shipping (Australia) Pty Ltd.

Guidance primarily provides undersea support services in conjunction with Royal Australian Navy mission specialists. The mission crew may consist of members of the Australian Defence Force and Australian Government officials. The vessel usually deploys for up to 6-week periods to support operations within the Australian area of operations before returning to homeport.

In December 2022, ADV Guidance, then known as offshore supply vessel Normand Jarl, was sold by Solstad Offshore ASA. Defence Australia announced the acquisition in April 2023 at a price of A$110 million. Following the purchase, the ship underwent maintenance and checks in Singapore and sailed for Australia in September 2023. The ship was renamed ADV Guidance while in Singapore and given a new homeport in Sydney.
