No sign of little boy who went missing almost two weeks ago

South Australian preschooler Gus has been missing for two weeks.

Police have thrown everything at the search but are no closer to finding him.

The four-year-old vanished from a sheep grazing station south of Yunta, 300 kilometers north of Adelaide.

Described by his family as a quiet but adventurous boy, they're desperate for him to be found.

But police believe there's little hope of Gus being found alive.
