Horsley's "snake hunter" is back in the Illawarra after his solo bush trek, falling short of his 100-day target after citing mental confusion and exhaustion.Andrew Ucles, 22, set out on March 21 armed with just a tent, a kayak, a hunting knife and emergency beacon, leaving behind a video saying he did not want to be located.Although he told media he was heading to remote Queensland, a month later his friends said he had gone to the NSW/Victorian border.Mystery still surrounds his self-described survival mission, which he said came to an end after 67 days."I won't disclose any information about the actual adventure itself, but what I am prepared to do is tell you what my goal and my aim is, and what the reasoning is behind it," Mr Ucles told the Illawarra Mercury yesterday.He said he was admitted to Mildura Base Hospital last week, however his visit there cannot be confirmed due to patient confidentiality.Mr Ucles refused to show any proof of the expedition, instead pointing to a documentary which he says is in production."I understand that there would be people out there saying 'there is absolutely no evidence that you've done that' ... What you will have to wait for is the documentary, because it is epic," he said."I'm going to bring it to you in an interactive, in an educative way, and in a way which promotes conservation."Mr Ucles attracted world headlines with his earlier story, telling media he didn't want to be rescued if the worst happened. He said yesterday he had deliberately led media astray about his destination."The last thing I wanted was to be disturbed ... I wanted to be in my zone, I wanted it to be focused and I do not want to have any sort of disturbance from anyone," he explained.Closer to home, Mr Ucles has become a renowned Michael Jackson disciple, pulling the late singer's iconic dance moves in clubs around Wollongong.Mr Ucles wouldn't reveal any details of the documentary or when it would be released."Money from the documentary will go towards the Australian Wildlife Conservancy," he said.
