What are the steps for FBA

Hey everyone, So I’ve recently decided to become a spend-time-with-the-family type dad. I’ve had this image for this product in my head for well over 4years. So this year I took the leap and began product research, ordering and getting all the papers in order. But now I’ve hit a rock.

I can’t seem to understand on how I should go about to get my product fulfilled by Amazon. I’m Australian based but I’d like my products to be fulfilled in America. I believe we have a fulfillment centre here in Oz but are they able to transport it to the US within the same price guide. Also what are the steps to even begin the fulfillment process. I believe it may be a comprehension issue on my part. Thanks everyone.
