Strength In Numbers (SIN) is a growing network of young women from all over the world who have come to live abroad in Australia. SIN began as an un-named fitness group which was formed for networking and support purposes among the au-pair community. Since running as a group for a number of months, the group has now been given a name in the hopes to extend a warm welcome to young women who are new to the area (or are looking to meet new people!)
