<b>Background/Objectives:</b> Type 2 diabetes (T2D) prevalence is rising worldwide. Despite numerous efforts to address the condition, many initiatives fall short due to limited consumer engagement. Involving people with lived experience in healthcare design is increasingly recognized as an effective strategy for improving diabetes management. <b>Aim:</b> To understand the unmet needs of people with T2D in self-managing their condition through the establishment of a Consumer Reference Group (CRG). <b>Methods:</b> The CRG was established using a standardized approach advised by Monash Partners, with specific terms of reference for consumer engagement. A face-to-face training workshop was conducted to develop consumers' capacity to co-design T2D interventions. Two focus groups were held to explore consumers' unmet needs and propose potential solutions. An inductive thematic analysis was performed. <b>Results:</b> Ten adults (three females/seven males; 58-78 years old) with T2D participated. Four main themes emerged: (1) misinformation; (2) limited guidance; (3) challenges in self-management; and (4) gaps in prevention and screening. Participants reported difficulties in maintaining motivation, balancing T2D management with other life commitments, and addressing mental health concerns. They reported feeling misinformed and inadequately supported by healthcare professionals and diabetes organizations, often relying on conflicting sources of information. Participants from culturally and linguistically diverse (CALD) backgrounds noted a lack of tailored dietary information. Proposed solutions included better training for primary care providers, reinforcing the role of diabetes nurse educators, expanding mental health support, and collaborating with CALD communities to provide culturally appropriate dietary information. <b>Conclusions:</b> These insights are critical for developing consumer-driven interventions that are responsive to the real-world needs of people living with T2D.
