Managing sustainable cotton production is becoming more difficult with the ever increasing demand on limited resources. In addition cotton growers are facing increased pressures to manage resources more cost effectively and to be more accountable for the impact that their decisions make on the surrounding environment. Computer based decision support systems and simulation models are being developed to provide cotton growers with the best information and tools available from research to assist with their management decisions. A primary aim of the decision support and modelling teams in the cotton industry is to utilise sound and up to date technology, and integrate this technology across different electronic platforms and mechanisms, and finally delivering it to the industry for adoption. We in the cotton industry are in an enviable position with an agricultural industry rich with successes and failures in computerised decision support. Therefore we can call on a number of approaches to assist acceptance, development and evaluation of its products and activities. One principle approach is to use multifaceted skills and knowledge, coordinated effectively with expertise and input of others when available. The first part of this paper will discuss the operation and means by which the decision support team, which now includes a number of people working on the crop simulation models to deliver decision support tools. The second part of the paper will address the significance of decision support and models to the cotton industry. Finally, the paper will present future activities being undertaken, involving both the decision support team and those associated with modelling
