A portion of each side element is shaped and dimensioned to accommodate a respective peripheral edge of the at least one surface element whereby the at least one surface element is retained within the side elements. Said portion of each side of the side element may 10 be generally curved or U-shaped in transverse cross-section to receive a peripheral edge of the at least one surface element. The perimeter length of the at least one surface element exceeds the perimeter length defined by the assembled side elements whereby the at least one surface element is held under compression within the frame assembly of the side elements. 15 In one embodiment, the pallet may comprise two spaced-apart surface elements. Preferably the pallet further comprises a support between the two surface elements. The support may be adjustable to vary the distance between the two surface elements. Preferably the support is adjustable to decrease the distance between the two surface 20 elements. Alternatively the support may be adjustable to increase the distance between the two surface elements. Preferably, in use, the four side elements are arranged in an array, wherein a first end of a first side element is located adjacent a second end of a second side element; the 25 opposing (first) end of the second side element is located adjacent a second end of a third side element; the opposing (first) end of the third side element is located adjacent a second end of a fourth side element; and the opposing (first) end of the fourth side element is located adjacent the opposing (second) end of the first side element. 30 -4 Optionally, the at least one surface element is continuous. Alternatively, the at least one surface element comprises a mesh or grid. Preferably, at least one aperture is provided in the, in use, ground-engaging 5 surface element. Further preferably, four apertures are provided in the, in use, ground-engaging surface element, wherein each aperture is shaped and dimensioned to facilitate use of pallet truck, or similar device. Most preferably, each aperture is shaped and dimensioned to allow the ground-engaging components, such as ground engaging wheels, of the pallet truck, or similar 10 device, to engage the ground during normal operation. Preferably, each side element is formed from a material such as metal. More preferably, each side element is formed from a metal alloy, such as steel. However, it will be seen that any material that can impart the required 15 mechanical strength may be used, and can be selected by one skilled in the art. Preferably, each surface element is formed from a material such as wood. More preferably, each surface element is formed from an engineered wood, 20 such as plywood. However, it will be seen that any material that can impart the required mechanical strength may be used, and can be selected by one skilled in the art. Preferably, the support is formed from a material such as metal. More 25 preferably, the support is formed from a metal alloy, such as steel. However, it will be seen that any material that can impart the required mechanical strength may be used, and can be selected by one skilled in the art. An embodiment of the invention will now be described, by way of example, 30 with reference to the accompanying drawings, in which: Figure 1 is a perspective view of a pallet according to a preferred embodiment of the present invention, depicting the pallet assembled for use; Figure 2 is a perspective view of a side element of a pallet; Figure 3A is a perspective view of a first end of the side element of Figure 2; -5 Figure 3B is a perspective view of a second end of the side element of Figure 2; Figure 4 is a perspective view depicting how the side elements and surface elements of the pallet of Figure 1 are assembled; and 5 Figure 5 is a perspective view of the in use underside of the pallet of Figure 1. Referring now to Figure 1 of the drawings, there is shown a pallet 10 according to a preferred embodiment of the invention. The pallet 10 comprises four side elements 12, two surface elements 14, and a support 16, which are 10 assembled to provide a base foundation, which can accommodate a unit load (not shown). Figure 2 is a perspective view of a side element 12 of the pallet 10. The side element 12 comprises a generally rectangular frame having two generally 15 parallel opposing sides 18, 18', and two generally parallel opposing ends 20,20'. Each of the opposing sides 18, 18' comprises an elongate channel, which is generally U-shaped in transverse cross-section. The opposing sides 18, 18' are oriented such that the open mouth of the "U" 19 of each opposing side 18, 18' is located on the same face of the side element 12, which is 20 defined herein as an in use, inner face of the side element 12. Each of the opposing ends 20, 20' is located adjacent a respective end of the opposing sides 18, 18'. A first opposing end 20 has an open face 21 at the respective end of the side element 12. A projection 22 extends through the opposing end 20 and defines a generally cylindrical elongate aperture 22', the longitudinal 25 axis of which is generally parallel to the longitudinal axis of the side element 12, Figure 3A. The inner surface of the projection 22 has a screw thread. A second opposing end 20' has an open face 23 at the in use, inner face of the side element 12. A 30 generally circular aperture 24 is provided adjacent the end 20' of the side element 12, and is located on a face of the side element 12 opposing the open face 23, Figure 3B, which is defined herein as an in use, outer face of the side element 12. A cross-member 25 extends between, and generally -6 perpendicular to, each of the opposing sides 18, 18'. The cross-member 25 has the form of a generally hollow cylindrical tube. Figure 4 is a perspective view depicting how the side elements 12 and surface 5 elements 14 of the pallet 10 are assembled. Each peripheral edge of a first surface element 14 is inserted into, and locates in; a respective opposing side 18' of each side element 12, via the open mouth of the "U" 19. The first surface element 14 thereby serves as an, in use, lower, ground-engaging face of the pallet 10. Similarly, each peripheral edge of a second surface element 10 14 is inserted into, and locates in; a respective opposing side 18 of each side element 12, via the open mouth of the "U" 19. The second surface element 14 thereby serves as an, in use, upper, load-engaging face of the pallet 10. Once assembled, an opposing end 20 of each side element 12 is in side-by 15 side relationship with an opposing end 20' of an adjacent side element 12, forming a contiguous assembly around the perimeter of each surface element 14. Accordingly, the generally circular aperture 24 of the opposing end 20' is juxtaposed in side-by-side relationship to the respective end of the projection 22 of the opposing end 20, such that the generally cylindrical elongate 20 aperture 22' and the aperture 24 are coaxial. A suitable fastening device, such as a screw (not shown), can then be used to fasten each side element 12 to an adjacent side element 12 via the screw thread on the inner surface of the projection 22 of the opposing end 20. Resultantly, the fastening device at each interface between adjacent side elements 12, is oriented substantially 25 perpendicular to the fastening device at an adjacent interface between side elements 12. Referring again to Figure 1 of the drawings, there is shown a support 16, which comprises a central body 28 and two external members 33. The central 30 body 28 is generally cylindrical in shape. An elongate aperture 30 runs along the longitudinal axis, and opens at each end, of the central body 28. The internal surface of the elongate aperture 30 comprises a screw thread. Each of the external members 33 comprises a disc 32 and a screw fixing 31. The screw fixing 31 can locate in the elongate aperture 30 of the central body 28.

-7 In use, the central body 28 is located between each of the surface elements 14. The screw fixing 31 of each external member 32 passes through an aperture in the surface element 14 (not shown) and locates in the elongate aperture 30 of the central body 28. Fastening of each external member 32 5 results in each disc 32 being brought sequentially into closer proximity with the central body 28. Once fastened, each disc 32 can be secured to the respective surface element 14 to impede unfastening of the disc 32 from the central body 28. 10 Figure 5 is a perspective view of the in use underside of the pallet 10. Four apertures 26 are provided in the, in use, ground-engaging surface element 14 to facilitate the use of a pallet truck, pallet jack, or similar device. Each aperture 26 allows the ground-engaging components of the pallet truck, pallet jack, or similar device to pass through the surface element 14, and to engage 15 the ground during operation of the device. Preferably, the perimeter length of each surface element 14 slightly exceeds the perimeter length defined by the assembled side elements 12. Accordingly, the sequential fastening of each side element 12 to, in turn, its adjacent side 20 element 12, will ultimately result in the application of a compressive force to the sides of each surface element 14 by the side elements 12 such that each of the surface elements 14 is held under compression within the frame assembly of the side elements 12. Preferably, the distance between the two surface elements 14 exceeds the longitudinal length of the central body 28 of 25 the support 16. Alternatively the longitudinal length of the central body 28 exceeds the distance between the two surface elements 14 Furthermore, the sequential perpendicular orientation of the fastening device at each interface between adjacent side elements 12 distributes the weight of 30 a load applied to the pallet 10 in a continuous manner around the perimeter of the pallet, reducing pressure being applied exclusively to a discrete location on the pallet 10, and the resultant chance of damage or destruction.

-8 The use of identical side elements 12 allows each element to be easily manufactured, and lends itself to easy assembly of the pallet 10. Each component of the pallet 10 can also be easily replaced following damage to the individual component, without the need to destroy or replace the entire 5 pallet 10. Moreover, the pallet 10 is accessible by a forklift, pallet truck, pallet jack, or similar device, from any of the four sides of the pallet 10. Accordingly, the present invention provides a modular system of connectable elements, which can be assembled to provide a pallet, which acts as a base 10 foundation, which can accept a load of goods for stable transportation. The uncomplicated and lightweight design of the present invention facilitates easy manufacture and assembly, and allows for simple replacement of individual parts following damage or destruction. The sequential manner by which the components of the pallet are fastened together bestows the pallet with the 15 mechanical strength required to accommodate the weight of a unit load, without damage or destruction of the pallet. The invention is not limited to the embodiment described herein but can be amended or modified without departing from the scope of the present 20 invention. Where the terms "comprise", "comprises", "comprised" or "comprising" are used in this specification, they are to be interpreted as specifying the presence of the stated features, integers, steps or components referred to, but 25 not to preclude the presence or addition of one or more other features, integers, steps, components to be grouped therewith.
