Thanks for your comment,

The silver contest is still waiting for any final entries as the window was open for 14 days as long as the person had upvoted the post.

After reading further into the information I could find its looks like the Australian Taxation Office treats Bitcoin as an asset, and requires a full record of Bitcoin transactions to be kept.

I'm not sure about the breakdown of how this works but that is what it seems to say in the media.

I will be doing a winners post in about 7 days time to share the results, please enter the gold bullion contest if you like :)
