Some of the factors influencing the speed of an international transfer include:
the transfer destination – whether the destination country has strong ties to Australia, and a large volume of money exchange traffic taking place, or whether it’s a more remote location with fewer ties. For example, transfers from Australia to New Zealand, the UK and India will often take less time than to less common countries
how much you want to send overseas – any amount over $10,000 has to be reported to AUSTRAC, the Australian Government’s anti-money-laundering agency. Larger cash transfers may be delayed by the need to comply with reporting requirements
the time of day transfer is initiated – obviously, the banking system only operates during business hours in whichever country you wish to send money to, so the international time difference (and weekends and public holidays) can influence how quickly your funds arrive at their destination
