The Sony A6000 is equiped with a multi interface shoe, “hot shoe”, but doesn’t come with a cover. To protect the interface from dust a hot shoe cover would be a small but wise investment.
After a bit of research, I bought one on eBay Australia a few weeks back for $4.29. Shipping to Australia was free and it took a couple weeks for the parcel to be delivered.
If you are interested the seller was “jacquelinelife” and the exact item description was “JJC Dustproof Hot Shoe Cover For Sony A77II A6000 A7R NEX-6 A58 A99 As FA-SHC1M (400764518473)“.
Here are a couple of photos of the hot shoe cover.

I prefer the look of the A6000 body with the multi interface covered and protected 🙂
