(Australia, chiefly, NSW, informal, sometimes, derogatory, humorous) The Northern Beaches of Sydney.

Origin: Derived from the stereotype that people from the Northern Beaches (an affluent coastal region of northeastern Sydney) are too entitled to leave the Northern Beaches without needing to. Furthermore, in Australian English (and other non-rhotic dialects of English), the terms insular and peninsula both rhyme. Origin information sourced from Wiktionary contributors (CC BY-SA 4.0).
