From their website Hike4hunger describe themselves thusly:
hike4hunger is an international community-led initiative to raise awareness about the global food crisis, build solidarity behind world hunger and encourage new behaviours in both the privileged and underprivileged worlds to close the gap.
To that end brave souls are setting off from 8am at Parliament House here in Canberra to walk up to the top of Mt Kosciusko. They plan to take 8 days.
Good luck to them!
