The Hawkesbury Sea is a location within Australia, presumably a reference to the current day Hawkesbury River before some unknown geological change.
- It is mentioned on the description of the Woomera B-5 Exotic Jumpship, the chosen ship of the Fighting Dharug: a group of Warlocks who "have control over the Hawkesbury Sea".
- It is mentioned in the lore for Tarrabah as the home of an unnamed Guardian who seems to preserve Aboriginal Australian culture.
