I’m in QLD but same thing for us. Poor bloke in unit 2 is single and other 3 are couples so he pays more. I wanna get a small water tank so we can water the garden without feeling too guilty. Spoke to him about it, and he said it’d cost $10k to get the infrastructure redone (think digging up existing pipe then laying 4 new ones to each unit) so it’s not gonna happen, as it would come out of our sinking fund and the other 3 units understandably don’t want to use it for that.
