There are several, already answered questions on this subject.
Scuba-divers have to equilize their ears during decent, because the middle ear doesnt automatically pressurize (unlike other body parts, like sinuses).
This is done by covering/squeezing ones nose using the thumb and index finger, and gently blowing air out your nose. The air, not being able to escape through the nose, will be redirected to the middle ear, thereby pressurizing it.

There are scuba diving classes and popular scuba diving areas in Sydney, Australia. Scuba diving clubs are not advertised in that area.
Yes you can. You must be careful when scuba diving. as you descend into the water, the pressure increases. you have air in your ears that feel this, and it hurts. they are called squeezes. to stop this, you must equalise the air spaces. to do this, you could hold your nose, shut your mouth, and breath out. or swallow, and wiggle your jaw. Most prefer the holding your nose one, but i personally like the second. If the squeeze doesn't stop, you must not go down further. do not force it, so ascend a little, and try again. if nothing works, stop the dive.
