Description of intervention(s) / exposure
Participants will be randomly allocated to an experimental group that attends the Interprofessional Clinic in the Clinical Practice Building at James Cook University, Townsville for 1 hour 2 times per week for 3 months. The experimental group exercises will include strength training, treadmill training, exercises, walking, bicycle training, skipping, and other aerobic exercises, sometimes with music, at a moderate intensity for up to 60 minutes including warm up and cool down, plus balance training and falls education (15 minutes) 2 days per week for 3 months. These exercises will be guided by a physiotherapist or exercise physiologist.
In the experimental condition, level of intensity will be assessed using Borg Rating of Perceived Exertion Scale (RPE; Borg 1982). Participants will be asked how hard they have worked during the class using a numbered scale (6-20 RPE) with brief descriptions. We will ask participants to exercise at a moderate intensity which is indicated by a score of 12-13 points on the Borg RPE scale. The balance exercises will challenge participants’ stability in standing by asking them to perform tasks that decrease their base of support, increase their movement of the center of mass and minimize the use of upper limbs for balance. Falls education will be integrated with balance exercise instructions for experimental group; and will consist of reading material (a pamphlet designed specifically for this study) for the active control group.
There will be weekly fidelity checks for both experimental and active control groups; including mini-surveys for experimental group instructor, and all participants. For the active control the physitrack application and weekly follow ups with a registered physiotherapist will also be used to monitor adherence to protocol.

Comparator / control treatment
Participants randomly allocated into the active control group will do stretching, flexibility exercises, and relaxation exercises (e.g. one minute of relaxation, with focus on the breath) at home for 1 hour 2 times per week for 3 months. Participants in active control group will also be provided with falls education, consisting of reading material (a pamphlet designed specifically for this study).
There will be an initial training session (approx 45 mins) at the Interprofessional Clinic at James Cook University with a physiotherapist or exercise physiologist to ensure the home exercises are being performed correctly. The physiotherapist will get each participant to perform each exercise individually and gone through the description of all exercises to ensure participants understand how to perform them. Participants will also be made aware that they can contact a nominated registered therapist at anytime if the have any questions.
There will be weekly mini surveys, use of physitrack app, and weekly fidelity checks by a registered physiotherapist There will be weekly mini surveys, use of physitrack app, and weekly fidelity checks by a registered physiotherapist to ensure adherence to active control protocol.

Summary
Brief summary
To our knowledge, there has never been published a controlled trial on exercise for PD in a tropical climate, despite regional areas such as Townsville having a high incidence of PD.
This phase I trial will add new data on that topic. Our previous clinical trials (Morris et al 2009;2015) showed that hospital-based and outpatient clinic-based physiotherapy were effective for improving mobility and reducing falls in people living with Parkinson’s disease. These trials were conducted in a temperate climate (Melbourne). There is a need understand responses of PD patients in tropical climates (such as Townsville) to structured exercises programs and to determine whether outpatient physiotherapy that comprises general fitness aerobic exercises plus balance training (45 minutes) and falls education (15 minutes) twice a week for 3 months in a gymnasium setting is more effective than home-based exercises coupled with falls education. It is possible that the exercise classes could reduce disability and improve mobility in Parkinsonism.
