@clj2012 Hey! I can only speak from my own experience. I got several calls from recruiters on my first week here in Sydney requesting for interviews (most were for IA jobs but some were for external audit). I attended most of the interviews on the second week then accepted one of the job offers on the third week. I started on a new job on the fourth week.
Salary wise, I think it was pretty okay. The job offer I accepted was on the lower end of the range of average salary for internal auditors (it was the highest I received!). But when they gave me the employment contract to sign, they increased it by $15K (annual which was a really nice surprise as I didn't even try to negotiate it. Baka di pa ako offeran pag nagtry akong makipagnegotiate! Hehe.
Until now, I'm still receiving emails and calls from various recruiters so I guess madami pa ring demand for IAs at least dito sa Sydney.
