If you are wanting to start up a new beehive from scratch then you need what is called a colony of bees. This contains 1 queen bee, possibly some drone bees but also thousands of worker bees. These can be purchased here https://BuzzBee.com.au/bees . You can not start up a new hive with just a queen bee, you need a whole community to support her to not only manage the hive, take care of the new brood but also to venture out to collect nectar and pollen.
