According to the ABS's (Australian Bureau of Statistics) latest measure, the average pay rises for full time employed Australians rose at an annual rate of 2.3%. (equates to merely $1380 a year that you will earn more, if you were on a $70k base annual salary). If you don't get it right early in your career, it is going to cost you a lot in the long run.
Salary Negotiation is about coming into middle grounds with your potential employer, so a win-win situation is established. To do this effectively, understanding how much you are worth and what the specific employer is willing to pay is crucial, which requires research, analysis, insider industry knowledge and experience.
Google searches only give you an indicative range of this. What employers are really willing to pay and how much you are able to negotiate will depend on a broad range of factors including their budgeted range, your experience in the role and industry, supply-demand, what the future looks like for the organization, market rates etc.
An effective negotiation prior to signing that contract, also helps you set the ground, so your hiring manager can help you succeed in your new role faster.
Hence it is critical to get every step of the job search process right.
