No need for smart answers. I read all of the comments, and spent hours searching on google. I’m not an idiot.
I discovered that companies that send 1000 parcels per year or more can have a contract with Aust Post - eParcel to send perfume through the mail by road only. The training is not for physically transporting the dangerous goods (driver training), it is about how to package perfume correctly so that it doesn’t leak, etc. If anyone is interested, you need to register a business account with Australia Post and get in touch with their eParcel team. You will be assigned with an account manager to guide you through the process.
I hope this information helps others.
