Our
Story – from vision to first reserve

South Endeavour was founded by Simon Marais in 2007. Simon was a lifelong conservationist deeply committed to the long term protection of the world’s wildlife and great natural places. In 2007 Simon, with support from a Swiss foundation,  bought  South Endeavour Station near  Cooktown on Cape York Peninsula.  This protects the headwaters of the South Branch of the Endeavour River. South Endeavour Trust was formed to own South Endeavour Station and that is where our name derives from.

Very sadly Simon died in 2015 leaving behind an extraordinary legacy.

That moment sparked South Endeavour — a long-term commitment to protecting Australia’s most important natural places. Today, that vision continues across a growing network of reserves in Queensland and New South Wales.

How we began

Our mission 

Our ethos has always been to do what is important for conservation that, for whatever reason, is not being done.  We have always sought to work with others, whether government or private, to strengthen conservation outcomes and to complement both the public and private reserve systems.

We see ourselves as investing in irreplaceable and highly valuable conservation assets for the lasting benefit of the Australian community. 

Early Growth

Building a Legacy

Over the past twenty years we have built our portfolio of reserves carefully and deliberately.  We have worked hard to seek out really important properties with exceptionally high conservation values and then to build strategies to enable their purchase.  The majority of the properties we now protect were not for sale when we first identified them. Rather, we approached the owners and sought to seek solutions to protecting the conservation values of the land.  In some instances it took many years from first approach to final purchase.  But when your time horizon is centuries, waiting a few years is soon forgotten.  Building our reserve portfolio remains unfinished business.  There is still so much more that we need to do.  But buying land is far from the end of the story.  Protecting, researching, restoring and deeply caring for that land is the real focus of our ongoing efforts.

Expanding Our Impact

From Small Beginnings to Protecting the Irreplaceable.

Our story is one of careful measured growth always being mindful of our long term financial sustainability and our capacity to care for our reserves as they need to be cared for.
