  • Industry and road‑safety write‑ups that track infrastructure data say research points to “around 8,000” roundabouts in Australia.
  • New roundabouts are being built each year as part of safety and congestion‑reduction projects, so any figure is an estimate, not a fixed number.
  • Canberra is often joked about as the “roundabout capital” because it has more roundabouts per person than other major Australian cities.

In practice, if you see a number online answering “how many roundabouts in Australia?”, treat it as a best‑guess snapshot , not a precise census.
