The evolution of Mitchell Marsh
The driver of the Australian team bus in Harare, a man called Kelvin, has thanked Marsh for "making his life."
Kelvin has two children and a third on the way. He earns $US500 ($A540) a month, with 60 per cent of that going to rent.
Sometimes he gets paid on time; sometimes it's a day late, or two, or seven.
Electricity cuts are a regular occurrence at their home, making cooking for his 12-year-old son and five-year-old daughter almost impossible at times.
Marsh heard Kelvin's story and marched straight into town, to buy the children backpacks and shoes for school. He also purchased a new mobile phone for Kelvin and a solar light and gas cooker for his wife.
