What money will be 'stuck' there? If you are referring to your superanuation it is not stuck, more that it can not be drawn upon until retirement. And that only applies if you are PR
because you can go back to Australia in later years pensionless if you withdraw it and then would be entitled to claim off the state. Only right imo because a pension is not a personal savings account to be withdrawn and spent at your own will. It is an investment for your old age.
