On 20 January 2024, Georgia Heffernan made her senior debut for New Zealand against Australia. With her sister, Kate Heffernan, already an established member of the team, the Heffernan sisters now became the third set of sisters to play international netball for New Zealand. The first set were their mother and aunt, Annette Heffernan and Maxine Blomquist. However, the Heffernan sisters are the first sisters to actually play in the same team at the same time.[29][30][31][32]
