I'm sorry that you are getting frustrated.
There is definitely nothing wrong with being new or Australian!
I didn't see your latest post, so I'm not sure why is was removed. I know that sometimes even if a topic isn't particularly "heavy" it might get shut down if the mods think it will lead to posters offering too much legal or medical advice. Other reasons posts get locked/removed are ranting, political/religious content not related to etiquette, discussion about illegal activity, or the poster is looking for advice that we are not qualified to give (meaning that anonymous internet posters cannot replace a qualified counselor/psychologist/social worker.)
Again, I did not see your last post. But if the mods felt that asking for advice here could do more harm than good, they had to remove it. If you'd like to PM me with the general content of your post, I could probably tell you more specifically why it was a problem.
And please don't take it a sign that you are unwelcome here. Even long term posters in good standing get threads locked. Sometimes the mods just err on the side of caution, which is part of the reason this stays such a nice board.
