It depends on how straightforward your application is. I done mine without an agent but mine was easy - only had to prove 3 years employment with the same employer, English test, skills assessment. You can start the ball rolling with the skills assessment - find out who would do your assessment (for me I used the AASW for social work - there's different ones - google it to see if you can find out). Have a look to see what you need to provide to have your skills assessed and see if you can get the info together. You can sit the IELTS test before applying but beware that it's then only valid for 2 years so check processing times. I would advise that you do some preparation for this to familiarise yourself with the tests before you sit it. As the previous poster indicates - 60 points is enough for an application but may mean it will take longer for them to process - worth checking this out to see if you need to aim for a higher score in the English test. You don't mention if you are applying for just you or a partner and/or children - you will also need to provide evidence of your relationship for each additional person on your application. Hope this helps a little - it's been a while since I done my application. At the time I applied with 65 points and was processed and completed within 5 months. Not sure of current processing times. Good luck!
