Just under a kilometre, and yet it looks pretty dense by the satellite photo (if the second star shown was where he was found) - without roads or visible trails. And yes, they had a lot of coverage in the search, including dogs.He was found just under 1000 metres (approximately 1/2 mile) from where he was last seen and according to the police he had on a "distinctive blue jacket" (which should have stood out in the bush a great deal). How had they not seen him for three days? According to the report, there were around 100 people comprised of aerial and underwater search crews as well as specially trained search and rescue volunteers.
He had all his clothes and boots, and thankfully seemed fine.
