Don't miss out on the opportunity to visit Watsons Bay, home to a quaint lighthouse and famous for its delicious fish and chips, the UNESCO-listed Cockatoo Island, or the surfer's paradise of Manly Beach, all of which are located within a 30-minute journey.

    The city also serves as a perfect starting point for those looking to explore some of New South Wales' most stunning natural wonders. Outdoor enthusiasts are recommended to explore the vast expanse of the Blue Mountains to the west of the city or bask in the golden sands of Bondi Beach, located on the eastern outskirts of Sydney.

    For those interested in taking a day trip, a visit to the Australian capital city of Canberra is highly recommended and can be reached within 3 hours. This historic city offers a wealth of attractions to explore, such as New Parliament House and Old Parliament House, which have been transformed into the Museum of Australian Democracy.

Be sure to arrive early to secure a table or take a seat at the bar to watch the expert chefs in the open kitchen at work. If you are in the mood for a steak, Porteno has everything you are looking for. The popular Argentinian steakhouse is one of Sydney’s culinary hotspots, with a line of eager diners often stretching out the door almost any night of the week. Among the many mouth-watering options on offer, the eight-hour wood-fired lamb and pig are must-try specialities.
