Concept & delivery

Banubanu Wilderness Retreat was established in 2005 by Trevor and his wife Helen who discovered Bremer Island while operating a fishing charter business in Gove, NT. Helen and Trevor have spent the last 10 years building Banubanu Wilderness Retreat to what it is today. They want people to experience all that East Arnhem Land has to offer including its pristine beaches and beautiful sunsets.

Banubanu is located on land that belongs to the local Yolngu community. Helen and Trevor have been given permission by the traditional owners to operate Banubanu on Bremer Island. Visitors are asked to pay a permit fee when visiting Banubanu which is paid to the traditional owners.

Commitment to sustainable living

Banubanu is an eco-friendly retreat that has been built with materials that make it one with the landscape. It runs on solar and wind power, the water supply is caught rain water and water-wise usage ensures a good supply throughout the year. It’s ecological footprint is tiny.


Banubanu Wilderness Retreat is located on Bremer Island, which is located 13 kilometres north of Gove on the Gove Peninsula. Gove is located in North East Arnhem Land in the Northern Territory.

Meaning of Banubanu

The name Banubanu was given to the large rocky outcrops at Banubanu Wilderness Retreat by Maccassan traders well before Europeran colonisation. Banu is a Persian name for a woman whereby Banubanu would mean women, which these large boulders represent.

The Owners


Trevor spent 30 years mapping the Northern Territory before moving to full time diving and fishing charters in Asia and the South Pacific in 1990. He moved to the Gove Peninsula in 2003 having long recognised the region’s huge and untapped potential not only for world class sports fishing but also as a place for those looking for any of the gamut of activities that come from the truly remote area experience.

Helen grew up in Alice Springs and worked with Indigenous communities in the Northern Territory for 17 years before launching Banubanu with Trevor in 2005. She runs the administration, finances and strategic marketing aspects of the business. Since its inception she has taken periods of time out to hone up on catering and business skills to help her manage day to day operations and to focus on the enterprise’s future direction. She is convinced of the value Banubanu can add to peoples’ lives.
