Visible crew/equipment: When the Jeep is flipping, in one shot, the door flies open and reveals that Ace is wearing jeans.

Visible crew/equipment: In the scene with the two Australians in the hut when the camera switches to a wider shot as soon as the bald headed guy says, "Disgusting rat!" the boom mic dips into view for a second.
