For pre 26 June & specifically applicants who submitted their application before 10 April 2010 to CIO Sydney, IELTS Academic score was acceptable.
However now it is risky as the Visa officer may not consider the new score for your IELTS if it's academic as these days academic is not acceptable for FSW-PR applicants.
You can use the academic score for your educational purposes, but it is tougher then general test so keep that in mind.
