Meggy, I've worked for a US company with a big presence in Australia, and they had a strong safety and welfare culture. I was able to make some presentations on my topics of interest at that time, Melanoma and Blood Donations, which are voluntary in Australia.
I can't see any harm in being proactive with the help-line information, and contributions to the employee health and welfare efforts. It might well work in your favour, if it's constructive and carefully put together, because your employers would see you making an effort.
