Thanks for your comments

Jade03 thanks as you noted it depends on how your employer sees you and I may have 7 years experience but with the right exposure and responsibilities. I was told last year that I should be a project / principle engineer with my experience and the part I play in the company.

Thanks for your useful information above though. What package would you expect on top of the 30k? I.e. housing allowance, car allowance, flights home yearly, medical cover, life insurance, schooling....
