Tony,
it's pretty easy, all u need is bank info (not required more than online bank transfer such as bsb, ur name printed on bank statement and bank account #)..
sign up at
https://www.paypal.com/au/
then, put ur bank account info, verify it, things will be really easier if u have online banking..(Orelse, u will need to wait your snail mail bank statement, but i believe you have online banking login)
verification process is simple, they will deposit 2 transactions in your bank account as a few cents, like 0.11 and 0.12 cents, they are totally random, when u saw those two transaction deposit into your account... just go back to paypal and insert those digits back.. then, it's verified and you are allowed to pay as much as you have in your bank account (could be a bit limitations at first though, but for me, i never use alot, so far so good with me), just like EFTPOS.. but it takes 3 days for seller to clear..
orelse, you use "add fund" function to add money in ur paypal, takes 4-5 days to transfer funds, then you can pay instant money.. (makes seller happier i guess)...
If you need more info, please feel free to let me know....
Perhaps, other members can give more suggestions too..
