A unique award-winning cruise to the tip of Australia

Sea Swift operates the last remaining working cargo vessel to carry passengers in Australia.

For 48 weeks of the year, our flagship vessel – the MV Trinity Bay – travels from Cairns to the Torres Strait and back again.

On this route the vessel carries vital supplies to a number of communities, and passengers get to experience what life is like in this stunning part of the world.

For five nights, the MV Trinity Bay traverses the stunning waterways of the Coral Sea and the Torres Strait, loading and unloading like a well-oiled machine.

Passengers experience to a mixture of stunning landscapes, cultural interaction, abundant history, life on the sea, and the camaraderie of cruising.

This cruise is so popular that it can be booked out 12 months in advance, and there are passengers that make it an annual pilgrimage, with some travellers having completing the trip an incredible 30 times or more.

In recent years, the MV Trinity Bay cruise has won numerous tourism awards and been featured in media around the world.

Due to the Trinity Bay cruise’s popularity, Sea Swift is now looking to expand our cruise operation, opening up passenger travel to other remote parts of northern Australia, creating more unique holiday experiences on working vessels.

The Trinity Bay Cruise has many options (timelines are subject to weather and tides):

  • Return – Cairns to Cairns (boarding Cairns on Tuesdays, arrive Horn Island on Thursday mornings, arrive Thursday Island on Thursday afternoons, arrive Seisia on Friday mornings, disembark Cairns on Sundays)
  • One-Way – Cairns to either Horn Island/Thursday Island/Seisia depending on your needs.  Both Horn Island and Seisia (Bamaga) have airports with service to/from Cairns, and there is a road from Cairns to Seisia which is open for the majority of the year.

How you tailor your trip is up to you with the certainty that you’ll enjoy the food, the company, the knowledge of how remote northern Australian freight works and a totally unique experience to go back and tell your friends and family about!

We are proud to offer our passengers a unique and exciting travel experience because we operate the only cargo-passenger vessel in Australia. It follows that passenger facilities should not be compared to a dedicated cruise liner. The vessel is first and foremost a working cargo ship, and is bound by strict health and safety regulations. Passengers should consider their suitability for ship-board conditions and for travel to isolated areas where medical assistance may be up to a day away. Regrettably, we are unable to accept passengers who have significant restrictions to their health, mobility, sight or mental capability. If you need advice about your particular circumstances, then please call us to discuss 1800 424 422.


Q. How early do I have to book? A. The earlier the better. For travel in the High Season we recommend  booking as early as possible.

Q. What if I have a food allergy? A. Please let the Cruise Supervisor know at time of booking and we will do all we can to cater for this.

Q. Can I bring a pet? A. No, but should you be on a holiday and have one with you, there are Pet Carers in Cairns who can organise a stay for your pet whilst you are on the cruise.

Q. Can I bring alcohol on board? A. No the Trinity Bay is a licensed premise and is bound by Responsbile Service of Alcohol legislation.  Should this not be adhered to the Master is within his rights to remove you from the vessel at his first available opportunity.

Q. Advertised prices have changed from what I booked, what happens? A. Quoted prices for the date of travel remain if you have booked and paid at the previous rates. Current advertised prices are for new bookings.
