Conditions, as far as I can tell: You have to be eligible for HECS (Australian citizen with a TFN, etc) and stay past Census date to get the FitBit, then you get charged $0 HECS.
"Foundations of Technology for Healthy Living is a fully online unit, designed to help you monitor your activities to live a healthier lifestyle. Free FITBIT®#: You will receive a free FITBIT® activity tracker as part of your participation in this unit (#conditions apply). Free Study*: Study is free for Semester 1 2015 with a HECS Scholarship (*conditions apply)."
They also have the Bachelor of Dementia Care HECS-free for units done in 2015 (you can exit after doing first year full-time with the Diploma of Dementia Care, if the funding doesn't continue into 2016).

"Fees: Study is free in 2015 with a HECS waiver (conditions apply). The HECS waiver is automatically applied when you enrol in the Bachelor of Dementia Care units for 2015. The waiver will show on your invoice a week prior to Census Date. There will be an annual SSAF (student services and amenities fee), as well as any possible textbook costs."
(…but you can normally throw SSAF on HECS (i.e. pay later) anyway.)
They also have the HECS-free standalone unit Foundations for Active Living but no FitBit is a deal breaker for me.

Edit: Please note that it says on the flyer "Clearly–in ATAR 60+ (not required for non school-leavers)".
A couple of my friends did this course and received Fitbits. Apparently they give you a code to use on Fitbit.com where you can order them.
100% free course. All done online.
