Bro, 2017 is only a couple of months away.  If you don't make the move soon, I reckon you will never make the move in the end. I faced the same dilemma because I was comfortable where I was, making more than enough doing what I did  and generally was extremely happy with my life in Singapore.  I ended up wasting two PR visas and it was only when I neared what I felt was  possibly my last throw of the dice (since I was going to be at the age where migration would be next to impossible soon),  that I decided to finally get off my butt and do something concrete about it.

Luckily for me, the new category of the significant investor visa appeared just in time to save my sorry ass. So now I have a whole chunk of my assets locked up in Australia,  and although that's a financial inconvenience, at least it allows me to continue being where I can maximize my business opportunities and still have one final chance to retire in Australia when it's time to call it a day

Check out DIBP Visa 188 convert to Visa 888. I used that route (and a good MARA registered migration agent).

2 businesses actually. I run a small boutique property development business - we mainly buy old houses or land and either rebuild/modernize an old house or develop houses on new land. Six months ago, my brother who lives in Sydney and I, together with some partners, started another venture. We are buying commercial properties to turn into medical centres.

Hope that helps.
