It's considered a wash if the purpose of the transaction is to create a tax loss. In my unqualified view, it is arguable that the capital loss is incidental to the transaction rather than its primary purpose. As long as you don't have a history of arguing with the ATO over the capital impact of your transactions you should be okay.

But seriously, the only person whose answer your should take seriously on this question is a licenced taxation professional.
