Studying in Australia offers international students more than academic achievement and a globally recognised qualification. It is a once-in-a-lifetime experience through which a student can develop independence, maturity, an understanding of other cultures, and the ability to see issues from different perspectives.

Study in Australia better prepares a student to work in today’s global marketplace. This is why several foreign companies recruit directly from Australian universities and vocational institutes. Many international organisations and companies employ overseas students with Australian qualifications because their exposure to the outside world gives them greater independence and maturity. With international trade barriers disappearing, great opportunities exist for those with the skills, experience and knowledge to seize them.

In Australia, international students can gain this experience in a safe, friendly environment and at an affordable cost.

IDP Education Australia is Australia’s leading international education and development organisation. IDP gives students unbiased, comprehensive information to help them choose the right course, the right institution and the right location for their individual professional and personal needs.
Education in Australia
Australia is the third most popular study destination in the English-speaking world, with more than 200,000 international students in Australian institutions across all education sectors: higher education, vocational education and training, English Language colleges, and schools.

The Australian government invests billions of dollars each year in developing Australian education and in university research.

Australian institutions have an international focus within their courses and activities. They exchange staff with institutions overseas, participate in international forums, and have partnerships and joint projects with overseas institutions and international research centres.

Australia’s universities have made important breakthroughs in modern technology and science while Australia’s vocational training system, which is based on industry standards, is used as a model for other Asia-Pacific countries.

There are universities in all major Australian cities and throughout regional areas of the country ranging in size from around 3,000 students to 50,000 students. About 20 percent of students enrolled in Australian universities are from overseas.

Many international students also study in vocational education and training colleges and institutes across Australia. These institutes offer qualifications that recognised in the workplace.

International students in Australia also study English language through courses offered by private organisations, universities and governments; in foundation courses to prepare them for university study; and within Australian schools.
