I rely on the ATO monthly FX Rates to convert transactions into AUD. These used to be available within 4-5 days and here it is the 21st of the month and they are still not published. Makes it difficult to lodge a BAS on time.

Hi @VetShop,


The monthly foreign exchange rates on our website are sourced from the Reserve Bank of Australia (RBA). These are updated by the beginning of the following month.


If you need to lodge your BAS and a monthly rate hasn’t been published yet, you can use an appropriate exchange rate from:

  • a banking institution operating in Australia (including the bank through which the foreign income is received)
  • another reliable external source.

Whichever rate source you use, it should be applied on a reasonable and consistent basis for your transactions.
