Kookaburra letterboxes manufactured by Chatterton Lacework  offer a wide range of models including the popular Federation Style letterboxes.

Federation Style letterboxes feature a heavy duty 90 x 90 aluminium tube post and a decorative post capital on top in addition to a heavy number plate and old fashioned scroll on the number plate. A large Aussie round top box is fixed to the other side of the post, and can accommodate large mail. 

Royal Park letterboxes feature a square large box with a fancy top and an Old English coat of arms on the face. The Brunswick model is very similar to the Royal Park, minus the fancy top and the coat of arms design on the front. 

All these letterboxes are available in a wide choice of powder-coat colours, especially in Colorbond colours used on roofing and garage doors. 

The demand for larger letterboxes has increased in recent years, primarily to complement the landscaping in many new homes.
