Yes
You can reach it directly or through E-bay.
E-commerce businesses are organizations/entities that sell goods/services online. Examples of E-commerce businesses are PayPal, E-bay and Amazon
All one needs to make a payment using PayPal is a PayPal account with the funds, and the e-mail address of the recipient of the money. To receive the funds all the recipient needs is a PayPal account associated with the e-mail address that was used.
PayPal is an e-commerce business founded in December 1998. Paypal allows consumers to safely transfer payments through the internet using their secure servers.
E-bay has sellers from all different countries including from Australia. You can choose a seller that is in your own country as well. Although items for sale change daily on e-bay, right now there are a total of fifteen Australian boomerangs for sale.
My suggestion is Liquidation.com, it kind of has a set up like e-bay, but different. You may buy and sell things to your desire. The site uses PayPal for incoming and outgoing transactions.
"The payment options include: PayPal, ProPay, Moneybookers, Paymate, Credit card or debit card, payment upon pickup and Bill Me Later."

Yes you can. Amazon (and most other web-sites) supports payment by Paypal.

If they pay with PayPal, they get to you Thank you page after completing the payment - you can place the download link there. (In this case you upload the ebook to your own server first.) Another option is to use E-junkie: they host the ebook and they also protect the link so that people can't just send it around and use it for free.
Usually the paypal account is your E-mail which you are used to sign up the site and the number is produced by the site when you finish your checking out.
