Hello Ollech, in regards to your questions, no I am not the same person who made Hispanic Australian, and before you mentioned this article I wasn't even aware of it's existence. This also striked me as odd as you have been actively making contributions to that article for a while now, but as you seem to be a new member you may not know all the little helpful features of wikipedia. By checking the history of a page you can see who created it and can verify I wasn't the user who created this page. Also from the follow up questions you have asked it seems to me you have an issue with the use of the word Latino. All these questions I will try to answer for you.

Spaniards and Italians are not Latinos because they are European and not from Latin America.

I can't give you the exact reference, as I no longer have access to it.

I'm not exactly sure what you mean by this so I will leave it unanswered.

In regards to a link there is actually a site called latinoaustralia.

No, there is absolutely no reference of him being Latino or identifying as Latino, and I don't think anyone will ever find one judging from what was said in that article. The reason he was added is because he is from Chile, but on further revision he could be easily removed from this page.
