Depends on where, when, how long, and how deep yopu want to go. A short while, in fairly warm water - just hold your breath and go under. Swimming goggles or a diving mask will let you see better.
A longer stay just below the surface, use a mask and a snorkel. If water gets cold, use a wetsuit, or a dry suit if it's really bad.
If you want to go deeper, use Scuba gear.
You only need your arms and legs, and a body of water to swim in.

you just need to have confidence and cup your hands when you swim move your legs as fast as you can and that should do it.
I don't believe you need a permit to swim in the great barrier reef.
Some infants can swim but they always need someone with them at all times. Also they need a special swim instrutor who helps them and give the ok. Never try to teach an infant to swim without qualifed supervison.
