Banking in Australia, including Internet banking, is relatively safe. You can withdraw cash, deposit cash, coins and cheques and conduct several other transaction types. Some banks even offer 24-hour banking facilities, which you can access by swiping your ATM card.
The fees and charges are different between banks and even between account types. You may have to pay a fee to use an ATM not owned by the bank you use. Your banking customer service representative will be able to explain all fees, charges and account limitations.
Something noticeably different about banking in Australia is that our banks are open and welcoming environments, some even with concierges that direct you to the appropriate assistant. The opening hours are reliable, and there is no machine gun-wielding military personnel guarding the premises, as is the case in many overseas countries.
Keep your money safe in a bank account. Australia is a customer-friendly nation with excellent banking facilities to protect and help grow your money.
