I've had many lengthy and convoluted discussions and conversations with various staff of the OFLC during which my views on the way they interpret and apply legislation was discussed but I don't think I can recall ever been asked specifically for my opinion via a survey.
My recollection is a bit hazy but I think I have read at their site that the OFLC conducts some kind of meeting/s with sectors of the community to help them ascertain "Community Standards". Although back in 2001 they apparently didn't discuss X18 with any of their Community Consultation panels - who knows if they have since then? The OFLC also go to some length to point out that their own staff represent a cross section of "community". Without wanting to state the bleeding obvious, I think the problem is that the OFLC is administering a crap piece of legislation - often without much consistency I might add.
I recently had the OFLC refuse to grant a Film Festival exemption for a film I represent here in Australia that had been classified X18 - the festival was already an age restricted event, the decision meant that an adult audience were denied the opportunity to see a sexy and very beautiful film that very much represented their "Community" - a film by a noted directer chosen by a panel of experienced film festival programmers for festival of world reknown. I wonder how that might be an accurate reflection of Australian "Community Standards"?
