not sure if your confusing visas and passports? maybe? passports "at least in my country" can be applied for from the department of home affairs (google the location closes to you).
Visas you need to apply for at your intended destinations embassy (google for this location). You need to consider wait time though. Examples:
1) I waited 2 months for my American Visa
2) I go for a Dutch Visa when travelling to Europe "and just adjust my travel plans to ensure i land there and stay a night or two" as in my country they have a turn around time of about a week or so (which is great). and you can use it to access most countries in the region.
3) Australian Visas im not too sure of, i know my business Visa takes about 2 weeks to sort out every now and then.
Another tip, the more money in your bank account the faster it goes "you normally supply a bank statement as a part of the process". They use it to ensure you can support yourself, etc. I think a good amount is normally in the region of about 30k ZAR (4K USD) a week will do (sure you can go less, depends on your accommodation though...)
if your question is whats your home address which will be presented on it, erm, yea, that should be simple
