Due to its proximity to Asia, reputation for good quality and relatively easy admission criteria and visa arrangements, Australia is a popular destination for international students to study abroad. All Australian universities actively seek international students, and students from overseas make up a high proportion of enrollments in many institutions as well as across the university system as a whole.

The most prestigious universities in Australia are known as the Group of Eight, and while they are not as prestigious as the top American and British universities, they are in general of a high standard, and seven of the eight are consistently ranked among the top 100 in the world. The standard of the other Australian universities is also generally very good, and few Australian employers are concerned about which university job candidates graduated from given the widespread confidence in academic standards across the system.
Most Australian universities are large public institutions, and there are only a handful of private universities (of which Bond University is the best-known). It's not unusual for universities to operate across multiple campuses in their home state or city, and several have international campuses as well. While most international students study in institutions located in Australia's major cities, some regional universities are very popular. Bridging courses and other support to settle into Australia are generally provided to international students, but are not always adequate.
Useful resources to research and compare Australian universities include the Good Universities Guide and the national government's MyUniversity website. The government's Study Australia website also provides information about Australia's tertiary education system and the application process for potential international students.
Australian students attend high school for six years, and enter university or vocational education at seventeen or eighteen years of age. (In Australia, neither "school" nor "college" are used to refer to tertiary institutions; they are referred to only as "universities", or "unis" for short - a 'college' might be a primary or secondary school, or more commonly a form of on-campus accommodation). Australian undergraduate programs are usually three to four years in length. A fifth year is compulsory in some professional undergraduate programs such as engineering, law, medicine and dentistry, with a sixth year being compulsory for medicine. Students in three-year degree programs who perform well during the three years can take an optional fourth year known as honours, which generally involves a year-long research project and requires the completion of a thesis, and would graduate with a bachelor honours degree. In Australia, the bachelor honours degree is regarded as a qualification above the regular bachelor's degree, but below a master's degree. Students enrolled in some four year programs can incorporate their honours thesis into their fourth year, while in others, the awarding of a bachelor honours degree is solely based on the student's GPA.
Postgraduate studies in Australia fall into two classes: coursework and research. Coursework degrees are generally at the Masters level, and in some cases involve a research component which requires the completion of a thesis. Students whose coursework Masters degrees involve a research component usually have the option of not completing the research component, and obtaining a Graduate Diploma instead. Research degrees are at the Masters and Doctoral level. To qualify for a PhD program, one is generally required to have either a bachelor honours degree of class 2A and above, or a master's degree with a research component. PhD programs are exclusively research degrees, and require the successful completion of a research thesis or a series of papers to graduate. However, unlike in most other countries, PhD students in Australia are typically not required to defend their thesis.
