If you're traffic started dropping last October, its most likely that you have a Penguin issue. After looking at some of your links, this is most likely the case. A quick look at your link profile shows that your top anchor text is "vuly trampolines australia", which doesn't seem like a natural way that people would link to you, especially when links show up on pages like this: http://www.linksjuice.com/7/Sports
I would recommend that you compile a list of your inbound links, and work to identify and manually remove any links which you paid to have placed or were part of an exchange. Document what you are doing and then upload a disavow file in webmaster tools and make a reconsideration request. Then focus on building some great content and EARNING real links.
From what I've read, it will take some time for the site to recover, but this is the correct way to address the problem. Good luck.
