I checked in Project Gutenberg Australia, and he's not there, I'm afraid: http://gutenberg.net.au/plusfifty.html
It's a great place to check out other writers hard to find elsewhere, such as George Orwell, Josephine Tey, etc ...

No, the fact that he died intestate doesn't affect copyright in the least, and the fact that something is on the US PG site simply means that it's in the public domain in the US, not elsewhere. That's why PG tells you to check before downloading whether or not it's in the public domain in your country.
