What is highest exchange rate in past twelve months Australian dollars to euros?

As of my last update in September 2021, the highest exchange rate in the past twelve months between Australian dollars (AUD) and euros (EUR) was approximately AUD 1.65 to EUR 1. This means that for every 1 Australian dollar, you could get around 1.65 euros at the highest exchange rate during that period.

However, it's important to note that currency exchange rates are constantly fluctuating and can change rapidly. For the most up-to-date information on exchange rates, it is best to consult a reliable source such as a currency converter or financial institution.
