When I ring strata they ask me to come through my real estate agent and real estate says it is common property and strata have to sort out.
As a tenant you are an “interested person” under strata law (Section 226), which means you can ask the owners corporation to do the job they should be doing anyway. They shouldn’t keep fobbing you off like that. If they want to get shirty about it, ask them if they are also aware of section 232 of the Act which allows an “interested person” to take them to NCAT to force them to fulfil their responsibilities.
Also you have certain rights as a renter, including that you have paid for the right to use the laundry. So you ae entitled to tell your rental agent to pressure the strata committee on behalf of the owner or organise a substantial rebate on your rent.
So it shouldn’t be a case of neither of them doing anything, it should be both of them doing something.
