Unfair strata levies and special levy

Our strata fees from April 1989 are so disproportionate my bedsit 26 sq value  $140k pays $115 per Month.  An independent 3 bed Villa 85 sq  value $430k pays $242 per month. there are 59 small units abd 110 villas.

In 2016 a special levy of $80 per month was voted in and was across he board not on entitlements. The smaller units have no way of outvoting and this has left us subsidizing the wealthier owners, this is the third year sor the special levy and talk of it continuing at a lower rate next year.

I cant see us getting tne entitlements changed 

What advice please
