I feel like selling it internationally is your best bet. Find someone in Australia and sell it to them for fair shipping.
Selling it locally is just going to make you tear your hair out. You’re trying to sell a popular device that has just had a refresh and a fair sale, outside of Facebook Marketplace or somewhere where a buyer is, quite frankly, not knowledgeable, I feel like your chances are just very slim.
On the other hand, Australian’s are looking at ~$1,200 AUD for a “new” high model that someone else bought and supposedly didn’t use.
You’d be doing the Steam Deck community a favor by selling it to an enthusiast without charging them extra just because they’re down under.
Yeah but so what? They can also go as low as $15 so it’ll just depend on the package size. I mean frankly, they are the ones who need it most and OP is clearly in a position where they are able to take some kind of L trying to sell it.
May as well be a good guy and pay it forward. Few around the states would be likely to buy it when the availability from official sources are just simpler and safer.
Besides, I bought a guitar from eBay from AUS. If they can charge me only $217 after shipping and the guitar itself, then a Steam Deck can get a nice price too ;)
