Migrant families often invite grandparents to move to Australia when babies are born. In order to provide support to their families, many of these grandparents have to retire from their own professional careers and migrate to Australia to start new lives. Some speak English as an additional language, with or without formal education, prior to arriving in Australia. Once in Australia, these senior migrants can only access limited government-funded English learning, and they are frequently left to capitalize on informal learning. This paper discusses a case study of two Chinese-heritage senior migrants and the role English plays in their lives, and grandparenting in Australia. We argue that having the English capability for everyday activity within the family is key to their overall well-being, and that drawing directly on their past experiences and learning strengths can enhance their quality of life.
