When I started thinking to move to Australia, Parents and my sister were my dependent, I didn't move until my sister got married. For parents they still live at my home in Islamabad, I requested my younger brother to move with parents at my house. My parents visit me in Australia for 3-4 months each year ( They cant stay more than that as they start missing Pakistan ). Then we visit Islamabad for at least a month each year. I am sure its not categorized as abandoning my parents.
