Strata levies – benchmark data?

Hi,

Can anyone point me to a comparison of Strata levies for similar facilities and geographic locations.  Clearly contributions to sinking funds might vary considerable depending on building age, conditions, facilities etc.

I was hoping to be able to compare the levies in our inner city, 23 level, building with other buildings having similar facilities (eg. no pool, no gym, two lifts, two bedrooms).

Some of our residents believe our levies are low, others think it is high (and we are inefficient), given we have virtually no facilities (aside from two lifts) our levies (not including sinking fund), are around $8000pa on the lowest levels and $12000pa on the higher levels.

We would like to determine if our building is being run efficiently or not.

Thanks.
