Description of intervention(s) / exposure
The Intervention Group: Participants receive a series of telephone calls over the 18-month intervention. Calls are delivered weekly and fortnightly for the first 6 months and monthly for the following 12 months. Calls will be tapered according to particpant needs. Participants receive a detailed workbook containing feedback on their baseline assessment, sections on physical activity, diet and weight loss, information on goal setting, problem-solving, self-monitoring and supports. Participants receive feedback following each assessment. Using the workbook during calls, participants work collaboratively with their telephone counsellor to set goals for physical activity, dietary change and weight loss. Barriers and supports are identified; confidence is assessed and problem solving is discussed as necessary. Participants are encouraged to work towards achieving overall physical activity targets of putting together at least 200 minutes a week of moderate-intensity physical activity, 3-4 sessions a week of strength training and to reduce their sedentary time; weight loss targets of a loss of 5-7% of initial body weight and diet targets of reducing energy intake by 2000kJ, total fat intake to less than 30% of energy intake and saturated fat to less than 7% of energy intake.

Comparator / control treatment
The Control group: After each assessment, usual care participants are sent a thank you letter that includes brief feedback on their assessment. Included in this mailing are standard, off-the shelf brochures, that are suitable for persons with diabetes, on a range of health behaviours (including diet, physical activity, alcohol) and a project newsletter that updates them on how many people are participating in the study and gives general health tips.
