Owners corp’s options re Airbnb

Need some advise. Living in complex of six units, one of which is rented. The Renter is doing air b&b with owners knowledge. Obviously costs such as water and maintenance increases, but all pay equally for these. Totally unfair. Told body corporate can’t assist so we wish to add a clause into body corporate at next AGM to place penalty on units involved in such activities, whereby they have to pay higher quarterly fees. Can this be done any ideas or indeed samples where has been done.
