OK. Or perhaps you've been refused a visa in another country (US, UK, AUS, NZ) or anyother.
If this refusal does not relate to visa refusal, it may be in reference to refusing to add the points for one year of your foreign work experience.
I see there's a recommendation to review information regarding refusal. I see that the officer has refused one of your three of foreign work.
Was your three years work with the same employer?
Did you have two years with one employer, and one year with another? If this is the case, I'll advise you send supporting documents for this job experience as there is a recommendation to refuse it.
