The Aust. No. 5 trailer is the Army trailer used behind Land Rovers. They have a single tubular drawbar, and a sort of ring-feeder at the rear. The wheels are inboard of the perimeter, under sqared arches in the load bay. They are amphibious, and appear the same as the British Sankey trailer. No brakes. The hood bow runs from front to back. These are common, and still in use.

The Aust. No. 4 trailer is the Army trailer used behind WWII Jeeps. They have a C-section A-frame drawbar, and a 2" bung in the rear, which can be replaced by a tap. The wheels are outboard of the perimeter, under flat three sided arches, when built by GMH-W (General Motors Holden Woodville or War Effert) and round arches, when built by Bantom (who made prototype Jeeps). They were also made by other companies. They are amphibious. The GMH-W units have no brakes, while the Bantom units have ratchet parking brakes with shock absorbers. The hood bow runs from left to right. These are common.

The Aust. No. 3 trailer is the same as the Aust. No. 4 trailer, except that they have a pintile hook at the rear instead of the 2" bung. These are not common.
