Myself and my wife did the first aid course GLC was offering (Melbourne based) and it was very good. We went in not knowing anything about first aid and really wanted to get a good understanding for when we were on the road, especially to protect Charlie our 1 year old. Over the 2 days the course covered a hell of a lot, much more than I was expecting we would cover but it was never done at a rush so we could absorb what we were learning and also practise over and over again the modules such as CPR and bandages etc. John who taught the course was also very good, having worked as an ambo for many years and then as a first aid educator, so he could get his point across easily and follow it up with examples of how it was done.
I havent done any other first aid courses to benchmark this one against, but I would highly recommend it to anyone looking to do one.
