If you want to come to Australia, getting registered is relatively straight forward. Apply for transcripts from the university, along with the usual documents such as a resume, references and proof of hours worked. You will also need your secondary school to write you a letter stating that you have been taught GCSE English for at least 4 years. Additionally, you will have to undergo a medical, which consisted of a physical exam, chest X-ray and blood tests. One thing to consider would be that Australia requires you to hold a degree in nursing and no longer accepts diplomas, unless a bridging course or further study can be obtained. You will also need to meet the registration requirements of the Nursing and Midwifery Board of Australia and the Australian Health Practitioner Regulation Agency.
Public vs Private
The working conditions are quite different compared to the UK, mainly due to the implementation of ratios. In a public hospital, the average number of patients a nurse will look after during the day is 4. In a private hospital it tends to be 5 or 6. Healthcare assistants are not as common in Australia, so you look after the patient in a more holistic fashion, although you do sometimes see nursing aids in public hospitals assisting with showers or fundamental care. There are also a larger number of enrolled nurses.
The majority of nurses work 4 days a week instead of full time, which is quite different from the UK. Conditions vary depending on whether you work in the public or private sphere. Generally, you are allocated a larger number of patients in the private system and are more overworked with fewer support systems in place. There is however still quite a difference in pay and conditions depending on which state you live in Western Australia is one of the highest paid, whilst Victoria is one of the only states with strict patient ratios.
