A barrier (162, 190) which is constructed from barrier structures (12A, 12B,..., 12N) each of which comprises a parallelepiped body made from mesh material with an interior in which are positioned deterrent sections (10, 50, 200, 200X), wherein the bodies are positioned in a succession of overlying horizontal rows which follow a barrier line.

A mast (10) which includes an elongate post (12) with a first end (14) and a second end (16), the first end (14) being pivotally secured to a ground-engaging support base, at least a first mechanism (22) to restrict pivotal movement of the post (12), a winch (26) which is attached to the post (12), and a cable (28) which is engaged with the winch (26) and which is secured at one end to an anchor (30), wherein the winch (26) is actuable to allow the post (12) to pivot, from an elevated position, in a first direction (54) which lowers the post (12) against the action of the movement restricting first mechanism (22), and which is actuable to pivot the post (12) in a second direction (56) which opposes the first direction (54) to elevate the post (12).

A MAST WITH A MECHANISM FOR PIVOTING THE ELONGATE POST
A mast (10) which includes an elongate post (12) with a first end (14) and a second end (16), the first end (14) being pivotally secured to a ground-engaging support base, at least a first mechanism (22) to restrict pivotal movement of the post (12), a winch (26) which is attached to the post (12), and a cable (28) which is engaged with the winch (26) and which is secured at one end to an anchor (30), wherein the winch (26) is actuable to allow the post (12) to pivot, from an elevated position, in a first direction (54) which lowers the post (12) against the action of the movement restricting first mechanism (22), and which is actuable to pivot the post (12) in a second direction (56) which opposes the first direction (54) to elevate the post (12).

An infill fence panel having a body which made from a mesh material and which has a first edge and a second edge opposing the first edge. The second edge forms an included acute angle with the first edge such that the body, from one side, has a wedge shape. The first edge is located on, and is fixed to, an upper edge of a primary panel which is of rectangular form and made from a mesh material.

A fence panel formed from two transversely extending arrays of spaced apart, parallel wires and a number of reinforcing elements wherein wires are welded together at points of contact in a first stage, and the reinforcing elements are welded to some of the wires, at points of contact, in a second stage.
