This Unit gives a broad perspective to students on Australian and International social work. This helps students understand the basic purpose and context of social work and explains the values, ethics, and ideals of professional practice in social work. The Unit covers historical and contemporary practice as well as the national and international professional bodies, which articulate professional standards and ethical codes of practice. The key ideologies underpinning the provision of welfare in Australia will be presented. This Unit contributes to understanding the role and value of social work in the community, its values, components, and areas of practice, and the complex and changing contexts in which students will practice.
