Convert Indonesian rupiah (IDR) to Australian dollars (AUD) at today's reference rate. Built for large amounts, with 30-day tables and a 12-month chart.
These figures use the same daily reference rate shown above, so they move when the rate moves. They are a quick way to size an amount of Indonesian rupiah in Australian dollars without typing it into the converter; for any other figure, use the IDR to AUD converter at the top of this page.

The inverse rate is simply 1 ÷ R, so the same reference rate answers the reverse question.

IDR/AUD pairs a major reserve currency (AUD) with a less heavily traded one (IDR). That usually means the rate is calculated as a cross from the major's quote against the US dollar and the minor's quote against the US dollar. Spreads on consumer products tend to be wider than for purely major pairs, especially outside the home market of the smaller currency.
Indonesian Rupiah is associated with Asia and Australian Dollar with Oceania, so each currency typically reacts to a different set of releases. IDR/AUD therefore tends to move when something specific happens in either home market: an interest-rate decision, an inflation print, a trade-balance number, or a political event that changes the perceived risk of holding that currency.
The number shown in the rate box is a daily reference rate: roughly the mid-market price at the time the public rate feed was published. It is a useful benchmark, but it is not the rate you would obtain at a bank, a card terminal, an ATM, or a money-transfer provider. Those providers add a margin to the mid-market rate (the "spread") and may charge a fixed or percentage fee on top. To estimate what a real transaction would actually cost, take the displayed reference rate and apply the provider's published spread and fee.
The 7-day and 30-day tables show one observation per day. They are useful for sanity-checking an unusual reading on the live rate against very recent values and for spotting any obvious trend over the last month. The 12-month chart on this page is built from monthly samples and is intended to show the general direction of IDR/AUD over a year rather than every short-term swing. For an intraday view of the same pair, the embedded chart further up the page draws on a finer-grained data source.
Like any exchange rate, IDR/AUD reflects the relative attractiveness of holding Indonesian Rupiah versus Australian Dollar. The most common drivers are:
Suppose the rate above is R. To convert an amount of Indonesian Rupiah, multiply by R: amount in AUD = amount in IDR × R. To go the other direction, divide instead: amount in IDR = amount in AUD ÷ R. The converter at the top of the page does this automatically and updates either input as you type. For an estimate of what a real bank or transfer service would deliver, subtract a typical retail spread (often a few tenths of a percent for major pairs and noticeably more for minor or exotic pairs) and any flat fee from the result.
If you arrived here looking for the inverse direction, the AUD to IDR page shows the same data presented the other way around. The guide on how exchange rates are quoted explains why the inverse rate is simply 1 ÷ R. To understand the gap between the figure on this page and what a bank actually offers, see the comparison of mid-market rates and consumer rates.

Multiply the rupiah amount by the IDR/AUD reference rate shown above. Because the rupiah is a high-denomination currency, most real conversions involve six, seven or eight digits — the common-amounts table on this page runs from 1,000 up to 50,000,000 IDR so a large figure can be read off directly instead of being typed in.
The rupiah has never been redenominated, so everyday prices carry several more zeros than in Australia. ISO 4217 lists IDR with two decimal places, but sen coins are long out of circulation and amounts are quoted in whole rupiah in practice. Nothing about the size of the number affects the conversion: it is still amount × rate.
The reference rate in the box above is a daily figure from a public rate feed. The interbank market itself moves continuously while Asian, European and Australian sessions are open, and the embedded chart on this page draws on finer-grained intraday data. For a large transfer, treat the daily figure as a benchmark rather than an executable price.
IDR/AUD is a minor cross rather than a major pair, so retail spreads are typically wider than on something like AUD/USD — often over one percent, before any flat fee. The guide to major, minor, and exotic pairs explains why the categorisation predicts the spread you will be quoted.
