Hi E,
PropertyInvesting.com has their 3Day Megaconference coming 7,8,9 May in Melbourne. I don't know what's the content this year, but if you go by the past two years is the best investment conference you can ever imagine! It doesn't only treat property investing, but all range of themes related to investing and wealth creation. If you can go I am convinced you wouldn't be disappointed. I have no idea what's the speakers and content for this year, but I supposse if you need to know you can always call the office and they might be able to give you some idea.
cheers
