There I was, sitting quietly on a park bench nursing my still sore knee, when I noticed two young girls in bright orange jackets striding along the road above my campsite.

Cars and a caravan arrived and the occupants all joined the two teenagers — Teagan and Olivia — for the last 100 metres.

Apparently it was Day 7 of a 300km walk from Devonport to Hobart to raise money to help Make-A-Wish Australia

All money raised (about $7000 already) will go to the foundation whose mission is to grant the wishes of children with life-threatening medical conditions to “enrich the human experience with hope, strength and joy”.

Despite their long day’s walk the girls were cheerful enough to set up a photo opportunity for their team, and I managed to hobble forward to get my own shot of them mounted on a topiary horse on the shores of Lake Dulverton.
