Just to add on this development above guys.....this is done when one is registering with NMBA (Nursing and Midwifery Board of Australia)....and just to show the significant role that NMBA is playing on one's migration journey to Australia, here is an excerpt from the source above:
ANMAC is responsible for making an assessment on an applicant’s work experience and qualifications to determine the applicant’s suitability for skilled migration. A health professional would obtain the migration skills assessment from ANMAC before lodging a visa application.
NMBA is the registration body in Australia which manages the registration of nurses and midwives in Australia. It is compulsory for nurses and midwives to be registered in Australia. You cannot work in Australia as a nurse or midwife unless you are registered with NMBA. NMBA also sets policies and standards for the nursing and midwifery profession. You can find out more about the NMBA from the Australian Health Practitioner Regulation Agency (AHPRA) website here.
In other words you will need to:
apply for the skills assessment with ANMAC to apply for Australian work visas or the General Skilled Migration visas; and
apply for registration with NMBA to work as a nurse or midwife in Australia.
