Book excerpt: More than three million students globally are on the move each year, crossing borders for their tertiary education. Many travel from Asia and Africa to English speaking countries, led by the United States, including the UK, Australia and New Zealand where students pay tuition fees at commercial rates and prop up an education export sector that has become lucrative for the provider nations. But the 'no frills' commercial form of tertiary education, designed to minimise costs and maximise revenues, leaves many international students inadequately protected and less than satisfied. International Student Security draws on a close study of international students in Australia, and exposes opportunity, difficulty, danger and courage on a massive scale in the global student market. It works through many unresolved issues confronting students and their families, including personal safety, language proficiency, finances, sub-standard housing, loneliness and racism.
