Just wondering how I can find out if money deposited in Citibank in Australia is covered by the guarantees.
You could ask Google Your Deposits with Citibank - Citibank Australia and http://www.citibank.com.au/global_docs/CustomerQ_A_Deposits.pdf
My understanding is the account must be opened in Australia for it to be covered by the Australian government. If you opened your account overseas it won't be covered.
