The hive i am looking a building is the 10-frame Langstroth hive on this website

2nd question

4th question
What is a recommended bee equipment supplier in Australia?

5th question
Is there anyone in Australia that makes these frames or has a jig to make them for this hive or plans for them?

Thank you for your time
Ralph
