Hi all, I am new to the forum so thanks for accepting me. I am looking for a starting point in beginning the process in moving permanently to Australia. A little bit about me - 34 years old, family of 3, partner and 3 year old child. I am in the finance industry and have been for 14 years - I am in a senior non management role with a certificate in a specialised area as my highest education. My partner if qualified in childcare and looks after children and has been doing this for 7 years. We would be looking to move to Melbourne. Where do I need to start to move this forward? How do I understand which Visa is the correct one to apply for etc. I also have family over in Melbourne and they have been there for some time. Thanks in advance. S
