The formula
How to convert AUD to HKD
The maths behind a AUD to HKD conversion is one multiplication, no rounding tricks. On 18 August 2026 that rate is 5.5816, so:
HKD = AUD × 5.5816
To go from HKD back to AUD, divide by the same rate. Put another way, 0.179161 Australian Dollars to the Hong Kong Dollar.
The converter at the top of this page does both directions and updates as you type. Every result is recalculated on the server as well, so the number you see is the number that gets stored.
About the Australian Dollar and the Hong Kong Dollar
The Australian Dollar (AUD, symbol A$) is the currency of Australia. The Hong Kong Dollar (HKD, symbol HK$) is the currency of Hong Kong.
The rate is set by continuous trading, which is why it rarely reads the same two days running. Everything on this page is a mid-market rate. Retail providers quote a spread around it and keep the difference.
Worked AUD to HKD examples
A price tag. Something marked A$50 comes to 279.08 HKD. Round to 279 HKD for a quick mental check while you are standing in the shop.
A monthly salary. A$3,000 a month is 16744.74 HKD — useful when you are comparing a job offer across the two markets. Bear in mind the rate moves, so a figure agreed today will not be the figure paid out in six months.
Going the other way. If you are holding HK$1,000 and want to know what it buys in Australian Dollars, that is 179.16 AUD. The converter handles both directions — use the swap button between the two fields.
Watch the margin. At a bureau charging 3%, your A$500 would fetch roughly 2707.07 HKD instead of 2790.79 HKD. That gap is what the mid-market rate on this page lets you spot.
Today's reading is 5.5816 HKD per Australian Dollar, recorded 18 August 2026. The daily feed updates it each morning without any action on your part.
At today's rate, 100 Australian Dollars come to 558.158 HKD. The converter handles any amount, in either direction.
Almost certainly not. What you see here is the mid-market rate, the midpoint of the market. Every retail provider takes a cut on top of it. The value of knowing the mid-market figure is being able to measure that cut.
