US FBI CLearnace

Hi

As part of the documentation for applying for Australian Citizenship, we are required to provide a penal clearance.

I was in US ( aprox 2 yr)and India (aprox 1 yr) After getting My PR

I think I need to meet the following criteria (Good Character requirements) : “Provide a penal clearance certificate from every country in which you spent more than 90 days”

Any sugession How i can get FBI Clearnce certificate in Australia ?
