exchange-rates-rba

Get currency exchange rates from the Reserve Bank of Australia

Retrieves exchange rates from the Reserve Bank of Australia's exchange rate datasets. Base currency is always AUD.

All datasets are cached after being downloaded for quick retrieval, and each dataset covers multiple years. Exchange rate data goes back to December 1983. A maximum of 11 datasets will be downloaded, totalling about 6MB. Datasets are only downloaded as needed, so you will likely only ever download one dataset (each dataset covers 3 - 4 years).

Some currencies are not available through the entire 1983 – current datasets, double check RBA datasets for if the specified currency is available throughout the required period. USD is available for the entire dataset period, excluding non-business days.

Install
