Celebrate Your Birthday Party on Sydney Harbour
A birthday party on Sydney Harbour creates memories that far surpass any land-based venue. When you hire a private catamaran, the boat is exclusively yours — no shared spaces, no noise complaints, and no strict dress codes. Bring multi-generational family and mates together, blast your custom playlist over Bluetooth, cook a deck BBQ, and drop anchor for a swim in Store Beach or Athol Bay. Whether it's a 21st, 30th, 40th, 50th, or 60th milestone, a harbour charter sets the perfect relaxed, festive backdrop.

A massive shout out to @buckingham_marine_services and every single tradie that’s been down to Alila over the past 8 weeks to bring Alila back to her former glory. 1000’s of man hours poured into this fine lady and we can confirm that all our blood, sweat and swear words have pulled together to make this beast stronger and faster than she’s ever been before. All made possible by everyone who’s been onboard with us over the past decade, most of whom are now friends, including agencies and the staff they keep. We love you all and hopefully you can experience Alila in the Whitsundays with your own friends and families in the upcoming years. We’re on a scout for some amazing locations along the way this time and look forward to sharing in the future. Love to you all T ❤️
Not many can survive out here, let alone thrive. The Swedish built this one tough and smart, thank you VV for sharing a total of around 3500 nautical miles around Port Jackson as the perfect co-captain, keeping the highest standards of safety, service and quality. 🫡
And autumn has arrived, best time of the year out here ❤️
Nice to take a day off the helm, and welcome to ESH Jayden! Jezza, if you’re watching, thanks again, that makes 9 charters and hopefully more to come. Love your groups, our preferred clientele.
