The points in the collection look the most extravagant of all the stone implements, that is because almost all (the stone ones made from quartz and chert) of them are made from coloured bottle glass, thus making them modern replicas of prehistoric implements. The size of all these points vary, the largest being approximately 17cms in length.
The points can be divided into two main types - the uniface and the biface. The uniface include the pirri points, which are shaped like an elongated leaf with either a rounded or a plain butt end. The pirri point has often been referred to as a smaller and shorter version of the leilira blade. The pirri points are are widely distributed throughout the interior of the Australia including central New South Wales, central Queensland, parts of South Australia, Central Australia and the Northern Territory. They are not found in Eastern Queensland or Eastern New South Wales or Victoria. The finest known pirri points known come from Lake Eyre, South Australia. They are often used as spearheads and also were used as ceremonial items.

The biface points are similar to that of the pirri points in that they are trimmed on both surfaces. The biface points usually include Kimberley points. The shape of these points can vary from leaf shaped to triangular in shape, they can also vary in size. Often these points have been pressure flaked, by pressing off small, thin flakes using a bone or wooden implement. These points are usually found in the Kimberleys Western Australia, upper Northern Territory and North Western Queensland. They are chiefly used as spearheads but can be used for ceremonies and rituals often as a surgical knife, used for incision type ceremonies.

The uniface pirri points can be seen in the Tula Regional Sequencewhile the biface Kimberley points are found in the Kimberleyan Assemblage.
The article by D.A. Casey, I.M. Crawford, R.V.S. Wright entitled The Recognition, Description, Classification and Nomenclature of Australian Stone Implements is a useful source for information about asymmetrical points.
