To all those asking questions like "what is the chances?" and "how much can I make?" I don't understand why you won't just try and apply? A lot of the the answers will depend on your industry, the company you apply to, your negotiation skill, your knowledge and experience, your personality, your timing, etc etc. Furthermore, market rates do change. Don't let random strangers on an internet forum discourage you.

There's absolutely nothing wrong for you to apply? Unless somebody can share why he/she wouldn't just try to apply? It will only take 10 minutes to edit your resume and send it out. As for potential salary, don't base your decision on what others are making, you will never be happy. Use that as a guide, but for the most part, you should factor the costs of living in singapore and derive a salary which can sustain your lifestyle similar or better than your lifestyle in Malaysia. If it is more than the so-called market rates, no worries, just apply. Because, if you have to downgrade your quality of life just to work here in singapore, then what is the point? For example, if you are living in a condo with a nice gym and pool which you use at least 3 times a week, eating out at chilli's a few times a month, but in singapore, you'd have to live in a store room in the red light district eating cup noodles every day. What is the point in that?
