The OG Aussie summer camp chaos where flour bombs solve everything and nobody goes home clean.
Season 1 • Episode 26
LatestOld Dan tells the boys that in the days of the Gold Rush, his father was convinced there was a hidden lode in Secret Valley. Beaver (Lofty) remains very impressed and decides to find the vein.
Secret Valley was a fictitious children's holiday camp in Bildarra which had been transformed from a run down ghost town into a resort. The children who worked and visited the camp often found themselves in battle against a gang of "bad" kids - Spider McGlurk and his gang from "Spider Cave". These battles usually featured flour bombs and other food related missiles and everyone inevitably ended up in a big mess.

Production
Ghost town transformed into working set—meta art before meta was cool.

Trivia, insights & behind the scenes
Secret Valley captures peak 1980s Australian children's television: minimal budget, maximum outdoor location shooting, and the belief that kids solving their own problems with mild property damage builds character.
Roger Mirams had already pioneered children's TV across Australia and New Zealand; this was his attempt to create a durable format that could work with rotating child actors, explaining the 26-episode single season structure.
