Would anyone be able to help with Australian customs clearance stuff?

I used Waybil to send the shipment.

If you are handling Australian customs clearance for your shipment, you would typically need to work with a customs broker or logistics company to ensure that the necessary documentation and duties are handled correctly. Since you used Waybil for your shipment, I would recommend contacting them directly, as they likely offer customs clearance services or can guide you through the process.
