Hello I am in Qld and I sold an item on eBay to a buyer in WA. I am just a private seller, not a business. Details not important for my question, but she has committed fraud, and eBay allowed her to keep the item ad took the money from my account to refund her. I have huge amounts of proof. I wish to pursue action against buyer. Can I lodge a QCAT application because I am in Qld, or do I need to lodge action in WA because of her location? Or would a letter of demand of some sort be better choice? Thank you if you can offer help.
