University of Western Australia
The university also offers the Bachelor of Philosophy (BPhil) course for high-achieving new students. This is a research intensive degree which takes four years because the honours year is an integral part of the degree (most other degrees last three years with the honours year as a separate degree). Students studying the course choose disciplines from any of the four bachelor's degrees. Places are very limited with on average only about 30 places offered to students each year. Thus there is a lot of competition for places and the cut-off admission rank is very high.
Bachelor of Science
In Australia, the BSc is generally a three-four year degree. An honours year or a Master of Science (MSc) is required to progress on to the Doctor of Philosophy (PhD). 
In New Zealand, in some cases, the honours degree comprises an additional postgraduate qualification. In other cases, students with strong performance in their second or third year, are invited to extend their degree to an additional year, with a focus on research, granting access to doctoral programs. 
In South Africa, the BSc is taken over three years, while the postgraduate BSc (Hons) entails an additional year of study. Admission to the honours degree is on the basis of a sufficiently high average in the BSc major; an honours degree is required for MSc level study, and admission to a doctorate is via the MSc.
