INTRODUCTION
Manufacturing broadly relates to the physical or chemical transformation of materials or components into new products, whether the work is performed by power-driven machinery or by hand. Manufacturing covers a range of production techniques ranging from computer-assisted production using robots to production of fine jewellery by hand.
The Manufacturing industry contributed 10% to Australia's gross domestic product (GDP) in 2007-08. In 2008-09 the manufacturing industry employed 9% of all people employed in Australia, with males outnumbering females by a ratio of around 3 to 1.
