Although many positive social changes have been achieved over the past 30 years, members of LGBT, Sistergirl and Brotherboy communities continue to encounter negative experiences with health and ageing service provision. In this article, 232 responses from a survey exploring ageing and care concerns and preferences among LGBT, Sistergirl and Brotherboy communities in Australia were analysed using chi square analysis. The largest proportion of participants were aged 55–64 years (26.4%, n = 61), with the majority residing in metropolitan regions (67.7%, n = 154). The three most frequently selected gender identities were cisgender woman (40.1%, n = 93), cisgender man (39.7%, n = 92) and non-binary (11.6%, n = 28). The three most frequently selected sexual orientations were gay (39.2%, n = 91), lesbian (32.0%, n = 77) and queer (17.7%, n = 41). While many concerns demonstrated no age-related differences, concerns regarding physical differences, respect and inclusion, finances and standard of care reflected higher levels of concern among younger participants compared with older participants. Preferences for receiving information reflected a desire for LGBT, Sistergirl and Brotherboy communities-specific resources for options for support from participants approaching retirement, that is, aged 55–64 (x2 (5, n = 178) = 11.08, p = 0.050); less desire for information provided through public health service services among participants aged 65+ (x2 (5, n = 178) = 15.58, p = 0.008); and variation in preferences regarding supports provided by LGBT, Sistergirl and Brotherboy communities. Results suggest that different generations of LGBT, Sistergirl and Brotherboy members may prefer to receive services and information in different ways. Further research is needed to understand how concerns, expectations and preferences are influenced across generations.
