Look for a professional translator for official procurement documents, and be sure to provide detailed models/parts models/clear photos. According to your requirements, I will purchase the original or sub-factory parts from the local dealer, check the model, check the quality, package and deliver. to Australia. The quotation includes domestic shipping in China, you only need to pay for international shipping. For long-term purchases, I still have a studio/warehouse that I can use to support sending directly to customers.
I have a suitable forwarder and the shipping is relatively cheap.
