Factual error: There is a a scene showing round bales of hay and as anyone in this district would know we never had those shaped bales out here in Parkes when man first walked on the moon, we only had the old rectangle shape bales of hay.

Factual error: When the dish is moving all its parts into place, some of the moving parts are seen labelled - with a type of label-maker that didn't exist in 1969.

Continuity: In the scene near the start when someone is looking at the photo of the dish (the photo is inside a manilla folder), the paper is hanging over the edge of the folder, but when it cuts to the close up the picture is in a different position.

Continuity: When they are playing cricket on the dish, all the shadows change from that shot to the next by about 30 degrees.
