How does this sound to put in my pay pal claim

The camera which I listed on ebay is “exactly” as I described and the photos of the camera and other items are what I sent to the buyer. The buyer has not once told me that he thinks it is a different model however! The buyer however has disputed that the camera and storage discs were purchased from an Australian Camera Supplier saying that it was not bought from an Australian Supplier. I purchased the camera and storage discs and camera bag on 12 August 2013 from My Camera Focus which is an Australian Business located in Western Australia www.mycamerafocus.com.au
The only question prior to bidding on the camera was asking if the receipt would be included in the sale of the camera goods. I stated in the listing that the camera was still under warranty. The warranty is covered by the supplier for the period of 12 months.
