Becoming a vet requires achieving two major academic milestones and some then go on to complete even further study. 

Entry to university to study for a Bachelor of Veterinary Science first requires completion of senior high school education with pre-requisite subjects normally including English, Mathematics, Physics and Chemistry. A final result of OP2 or better, or its equivalent, is then required to be considered for direct entry. Some high school leavers with lower results or without the required subjects have gained entry to Veterinary Science after first completing a year of a Bachelor of Science before then crossing over. You should contact the relevant tertiary entry board in your state for up-to-date requirements. 

Once at university, a veterinary degree requires five years of full-time study to complete. The earlier years focus on foundations in chemistry, biology and physiology with practical exposure to farm work. The later years shift the focus on to medical and surgical subjects with practical exposure to more clinical-type roles. 

Once completed, the graduate veterinarian is then qualified to practice in large or small-animal clinics, to fill academic, government or industry positions or to go on to complete further study towards higher qualifications.
