I read a bit about the grammar of both of those, and read aloud the paragraphs on Omniglot to get a feel for the sound, and so far I don't like Warlpiri much, but Pitjantjatjara is quite cool.
Although, so far I am most interested in Awabakal. I love absolutive-ergative languages, and this one is very unique, being from Australia. I've never even thought of studying one until a couple months ago! Awabakal's grammar is very intriguing, so when you are able to provide lessons, my partner and I would gladly be on board.
By the way, how is this language being constructed? I would imagine there aren't very many texts available in it from when it was alive.
What books exist for learning/reading about it so far? I have seen you mention a dictionary with about a thousand words in it.
Also, do you happen to know what the diacritics in the example on Wikipedia represent? Or anything about the phonology?
