Hi! just wanted to say welcome back to Australia, and don't feel alone because with first birth EVERYONE has no idea what's going on! But like others have said, u've come to the right place! The other thing to consider is looking at having a Doula (Birth Attendant), they are there to support YOU, to 'mother the mother'. You do have to pay for these, the rate varies, I know mine charges me $500 which includes a few visits during pregnancy and a couple after as well as she'll be there for the entire labour. My husband actually found her invaluable when our first daughter was born, she was able to kick him out to get some fresh air and he knew I was in good hands

I won't lie, having a baby is normally painful, but it's pain for a PURPOSE! It's like a marathon runner getting sore muscles and feet...they're achieving something at the same time, so are we when we are going through labour, we are bringing a baby into this world! And the pain is honestly instantly forgotten when u hold that beautiful baby in ur arms!! There are a huge variety of pain management options other than drugs too, water is definitely a popular one, massage, heat packs, TENS machines, different labouring positions, I know some people also use Calm Birthing and Hypno Birthing techniques, may be worth reading up about them too if that interests you

As for the questions, just write down any you think about, u've still got time to ask more questions as u think of them Congrats on your pregnancy all the best and hope you can get the Water Birth you are after!!!
