First Aid Brisbane?

I’m looking to do some first aid courses, for personal development for work (office work, nothing hectic).

I know there are more expensive ones like St John’s, but considering I’m not out here trying to be a nurse, will the cheaper ones suffice?

I’ve been getting ads for a new financial deal from Australia Wide First Aid and it’s literally half the cost of St John’s, and super close to work. I can’t see any indication as to why either. It’s accredited and covers the same stuff.

Thoughts? Anyone done one through them?
