For BNA–SYD we show about $529 on the low end and around $915 as a more typical one-way economy total, USD, last reviewed August 2026. Long-haul sale banners expire; a $529 one-way is a planning floor, not a coupon. Taxes, bags, and seats change what you pay on the seller site.

Distance and time BNA–SYD
Nashville and Sydney sit about 9,210 miles apart. If a nonstop is missing from BNA, timed itineraries near 18.5 hours of flying usually mean one long-haul plus a shorter feeder — not two equal hops.
Sydney is about 16 hours ahead of Nashville on standard time (America/Chicago vs Australia/Sydney). Arrival clocks on SYD are local. That matters more on this pair than on a same-zone hop.
Most Nashville–Sydney journeys connect rather than fly nonstop from BNA. Timed one-stop itineraries often bank at Los Angeles International (LAX), San Francisco International (SFO), Seattle-Tacoma International (SEA). That is a pattern, not a promise for your dates. On results, sort by fastest if you care about layover pain, or cheapest if you do not.
