Can an executor of a Will cheat when some of the assets are in Australia and will is not filed there. Filed in California.

My dad passed away Feb 2nd(step mom already passed). His Will was filed in California. The executor is a close friend of my parents. However she has been very vague with me about details and doesn't want to talk to me on the phone. She told me I will be getting something in Australia- but it will take a very long time to sort out, since she has a family member acting on her behalf and asking the court for probate etc... since the Will was filed in California not Australia. She threatened me tonight making me feel like she may cheat me out of what is supposed to be mine. Is this possible? Is there anything I can do? Also, she refuses to give me the attorney's number- that is handling the rest of the Will in California. Is that legal? I feel very much in the dark.
