I am a qualified phlebotomist. (medical scientist now lol) You really want to get the cert III in pathology. I qualified through tafe southbank in brisbane- a great course if you are local and includes 2 weeks work experience. Even if you have a cert III the big companies generally have their own qualifying on the job course that you will have to complete regardless- the cert III just makes you more competitive for the position. I would probably approach a few local companies about positions available before enrolling- the Cert III is expensive and may bw unnecessary HTH
