I just wanted to take this opportunity to say hi to all the members of AIDN. I am a passionate supporter of ensuring that Australian companies have the chance to compete for work on all Australian Defence programs and that you all can compete in a fair and equitable manner. This should be an exciting time for Australia’s Defence Industry and I know that many of you are being frustrated. My role is to advocate loudly and often for you. I will call out poor behaviour and praise good work. I intend to be heavily connected to CASG and Government ensuring that you and your businesses are not forgotten nor disregarded.
