Originally founded in 2005 as The Sandbar and Grill, the restaurant was originally created as a community hub for the newly built seaside town of Casuarina, on the northern coast of NSW. The Sandbar and Grill operated successfully for three years, but closed its doors in 2009. The current owners renamed the restaurant Osteria, after their love of the simplicity and the perfect emphasis placed on good food, wine and produce at all of the Osterias found scattered throughout Italy.

Initially reopened as an Italian inspired meeting place for family and friends in the region to enjoy locally grown produce, great food dishes, and delicious wine, the venue has now evolved into a sophisticated, well-known, self-sustainable hub.
