PR rejected. appeal?

[jianha]

I got rejected our family PR.
S.Korean couple: 37 years old
Three year old son.

We stayed and worked since 2011
My husband is working as IT
I am working as sales Both salary over 10,000

Do we need to appeal? Be honest, We don't have any of profile changes. My friend said we can appeal with cover letter but I am not sure. Can be a higher chance If I hire agency?

Please give us an advice.

Appeal is not useful if you do not include significant changes to your profile, etc.

Agencies are not needed and they will produce the same result as of what you can do on your own

Korean who are not ethnic Chinese get lumped with others racially and others has only about 500 PR approved per year. You're chances are very low.
