Question 1

How much purchasing power does 100 AUD in Sydney represent in London?

Accepted Answer

Per World Bank PPP, 100 AUD in Sydney (Australia) has roughly the same spending power as 49 GBP in London (United Kingdom). This isn't a bank exchange rate — it's "how much local currency you'd need for the same standard of living".

Question 2

Why is this different from the exchange rate?

Accepted Answer

Bank rates reflect currency markets; PPP reflects domestic goods and services prices. The two often diverge meaningfully, especially between developed and developing economies.

Question 3

How accurate is the Sydney–London comparison?

Accepted Answer

World Bank PPP data is country-level, so the same figure applies to every city in a country. Sydney stands in for Australia and London for United Kingdom. Monthly refresh with a 12-18 month publication lag.
