Mark Gresser is walking more than 5,300 kilometres alone, from the westernmost point of Australia to its easternmost edge.

He began his journey at Steep Point in Carrarang and is making his way through the outback with the goal of reaching Cape Byron. Along the way, he hopes to raise money for youth mental health organisation Batyr.

Travelling solo, Mark is pushing a self-made cart carrying his most essential supplies including food, water and a tent.

However, the journey hasn’t been without setbacks. Mark has spent the past month stranded in the small outback town of Tibooburra due to record-breaking heat and heavy rainfall.

Mark tells us how his journey is going so far and discusses some of the challenges he has faced along the way.
