As you are all adults you cannot be sponsored as an adult to go with them.
If you have no other family in the US once they are in Australia and have been granted permanent residency they may be able to sponsor you on a last remaining relative visa but this is all after they have become permanent residents.
I am sorry I cannot give you anything more positive.
