The Bachelor of Medical Laboratory Science is studied at university to become a medical scientist. In this role you wouldn’t have patient contact because you perform testing on pathology specimens in a laboratory.
You might be eligible for a Commonwealth Supported Place, which means the Australian government pays for part of your course costs.
