It was created in the early 1970s by a group of exceptional horsemen, led by R M Williams, and follows drovers routes through 18 National Parks from Cooktown in Far North Queensland to Healesville in Victoria.

Why would one mad pom fly to the other side of the world to journey in Australia's pristine wilderness with three wild horses captured by passive trapping in Guy Fawkes River National Park?

To test himself, his horsemanship, the courage and loyalty of these wonderful heritage horses, to leave the comforts of home and hearth behind and expose himself to the elements and to journey not only across a continent but the length and breadth of his own psyche and soul.

An avid horsemen from childhood, Garry Parker understands horses. He has worked with them all his life. This test will challenge everything he knows about horses and take him to levels of horsemanship hitherto undreamed of. To take wild horses back into their own historic domain, among other wilderness areas, and ask them to stay bonded to their human companion, rather than bolt back to the herd. To test the strength, agility and versatility of the horses used in the First World War's International Expeditionary Force - the original War Horses who are Australia's Living History.

Garry wants to put Australia's Bicentennial National Trail front and centre and onto every Aussie's bucket list, to promote awareness of the incredible heritage horses (often nicknamed brumbies) as an untapped natural resource, and to raise money for UK defence force charity Help for Heroes. 

It's a challenge few would contemplate and even less complete. Will Garry make it? Has he the mettle? The Pioneer spirit? The courage and commitment to travel through inevitable hardship, adversity and challenge to succeed where others have failed?

Only time will tell . . .

Garry has begun his Australian journey and has less than 11 months to complete this mammoth trek.
