Sailing from Thailand to Australia around August

Hi, I'm Caroline! I am traveling Southeast Asia until August, and in Burma, I will be working as a sailboat captain for a month. With this experience, along with being a Divemaster, and for just wanting to have an adventure, I am very interested in sailing from Thailand to Australia. I would want to do this around August, but I do not have boat, and would really like person/people to do it with. Message me or whatever! Think it could be awesome.
