A film that takes a bit of liberty with the truth. It's not a comedy, as such, but more a typical Australian “tall story” (where the facts are stretched to make things more interesting), but it's done with a sense of humour; a subtle one.
The story is about the Parkes radio telescope dish (in the middle of a sheepfield, in a country town), and how it was used to support the NASA mission to the moon (it's still used, to this day), providing telemetry when our side of the planet was the best spot for it.
Unfortunately, just before it's needed, a fierce windstorm brews up, forcing them to lock the dish into place. Prior to that, they lose track of the space mission, after a power failure, and fake local coverage of it for a visiting American dignitary. There's a few amusing moments for how they greet the American and Prime Minister, too.
