We've been receiving a lot of physical mail from a tenant who no longer lives in our building.
The mail is unwanted by this tenant, and they are unwilling to contact all the senders to update the address, as they consider it non essential (mostly junk).
According to the website, Australia post will not be able to halt mail coming to our address unless this ex-tenant contacts all these senders and updates his details.
Originally we were redirecting the mail, but Australia post was charging us to do this. So we've been trashing the mail since then (yes, this is legally questionable, if not outright illegal, we're well aware).
It seems like a terrible waste, and is frustrating to have to deal with this.
Any advice would be much appreciated.
With an overwhelming number of responses telling me to use the RTS method, I'll go ahead and start doing this. I'll close this thread for now, many thanks for your input!
