A FOUR-year-old boy who went missing in the Australian outback has been pictured for the first time as the search enters its sixth day. August "Gus" Lamont, disappeared from his grandparents' remote property on Saturday, only leaving behind a single footprint. The boy was last seen at the homestead about 30km south of Yunta wearing a grey hat, a blue Despicable Me-branded shirt and light grey pants. Local cops said: "It's a very similar boot pattern to what Gus was wearing when he went missing." On Thursday, his worried-sick parents released a picture of Gus wearing a Peppa Pig shirt reading "My Mummy".
