As EFI systems do not have an accelerator pump as such, you can't flood the engine unless there's something radically wrong with it.
Actually you can flood a EFI car especially in the cold. I assume it doesn't get very cold in AU. In fact my wife's Nissan flooded the other day when it was -32° C and her X-Trail was outside for a couple of days.
On an EFI car, holding the pedal all the way down tells the ECU to not run the injectors at all to help with a flooded engine.
