 This thesis describes theoretical and experimental research conducted by the author to determine the mechanical properties of the timber species cypress pine in the unseasoned "green" condition as supplied from New South Wales and Queensland.

 Approximately 340 sticks of cypress pine were tested in two size groups, 75x50mm and 125x38mm. The material was tested initially in a 3 point configuration in the full delivered length to obtain a comparison of the flexural stiffness exhibited by both size groups. The sticks were then divided into two groups in each size for bending and tension tests. It was ensured that suppliers had equal numbers of sticks in each test. The bending tests were completed in a 4 point configuration with sticks half the original length.  The tension tests were conducted with the full 3.5m lengths. The sticks were checked for size, moisture content and density.
