If you are in melbourne these guys remove bee hives.
To ensure that feral honey bee colonies and swarms are not unnecessarily destroyed, The Beekeepers Club offers a Swarm Collection service, with each swarm collected being inspected and treated as appropriate before being relocated.
I have two feral bee hives where I live and the bees do not cause me any grief
but if you disturb them without protective safety gear and a smoker device you will be in a world of pain as bees are vindictive if disturbed.
or look up apiarist or bee keeping clubs to find someone to remove the hive.
