The incredible story of a father and son who survived crocs and trigger-happy farmers during 16,000km trek around Australia to save kangaroos - and the sobering reason their trip came to an end
David and Mark Howison walked around Australia in 1973/74 to raise awareness about the plight of kangaroos
The father and son realised during their 16,000km trek that kangaroos were abundant and did not need help
Along the way they encountered aggressive wildlife - and humans - as well as road trains and dangerous roads
Mark Howison has now written about the pair s extraordinary adventure in a new book called 13 Pairs of Boots
