You’re first step is to notify your landlord/property, manager. Tell them the situation.
Request that they have the strata rectify the problem ( that’s going to take some time)
Ask for a rent reduction for the in convenience or ask to terminate the lease because of the noise.
Mention, politely that you will seek an order from fair trading for either a rent reduction or a termination of the lease.
Allow the landlord about two weeks for a response, then go to fair trading
