IRONMAN 70.3 Western Australia
A flat, fast half-iron on the sun-drenched shores of Geographe Bay — one of the most beginner-friendly 70.3 courses in the Southern Hemisphere.
Where it is
Busselton, Western Australia, Australia
Is this your race?
This is one of the more welcoming 70.3s on the calendar. The bay is sheltered and reported calm, the bike rolls along flat coastal roads, and the run hugs the foreshore — no mountain passes, no brutal climbs. December race-day temperatures are typically mild (around 16–23 °C), which keeps heat stress manageable. Beginner fit 4/5: 70.3 baseline 3, +1 sheltered calm bay swim with wetsuits likely permitted, +1 flat bike and run, +1 mild race-day weather — clamped to the 70.3 maximum of 4.
✅ You’ll love it if…
- You want your first 70.3 on a forgiving, flat course with a scenic swim
- You thrive in mild summer weather and love a coastal atmosphere
- You enjoy a race that doubles as a beach holiday in Western Australia
- You want a well-established IRONMAN event with solid race-day infrastructure
⏳ Build up first if…
- You have not yet completed an Olympic-distance triathlon — aim for that first
- Open-water swimming still feels unfamiliar — log at least 10 open-water sessions before race day
- You have fewer than 16 weeks of structured training remaining — a 20–24 week build is ideal for a 70.3

The course, demystified
Three legs, all flat, all scenic — the Busselton Foreshore is your anchor point for the entire race. You start and finish within sight of the iconic Busselton Jetty, one of the longest timber jetties in the world.
Respira y flota (breathe and float) — the start is in Geographe Bay, a sheltered sea bay off the Busselton Foreshore near the famous Busselton Jetty. Event listings and the City of Busselton describe the bay as calm, and the reported water temperature is around 19 °C. Check the official race guide for the 2026 wetsuit ruling, as it has not been confirmed yet.
The bike course follows flat coastal roads and winds through surrounding bushland. No significant climbs are reported, making this a course where you can settle into a steady effort rather than grinding up hills. Total elevation gain has not been verified by available sources, so treat it as a planning unknown.
The run is a flat, multi-lap course along the Busselton Foreshore and beachfront promenade, passing the Busselton Jetty. Crowds and scenery make this one of the more enjoyable run finishes in Australian triathlon.

How to fly in
Fly into Perth Airport (PER), the nearest international and domestic hub. Busselton is roughly three hours south of Perth by road, according to event listings. Car hire from Perth is the most flexible option for transporting a bike and gear; check whether a direct Busselton–Margaret River Regional Airport (BQB) service suits your itinerary as a shorter transfer alternative.

Where to stay — by what matters to you
Foreshore & Jetty precinct
Staying within walking distance of the foreshore puts you steps from transition, the swim start, and the finish line. Ideal for race morning logistics — no car needed on race day. Book as early as possible; this area sells out quickly for race week.
🏨 See stays · affiliateTown centre
A short ride or drive to the foreshore, with more accommodation options and easy access to supermarkets, cafes, and bike shops for last-minute needs. A good fallback if foreshore properties are already full.

Bringing a support crew?
Busselton is one of the best spectator races in Australian triathlon. The flat foreshore layout means you can cheer your athlete at multiple points without a car — just walk or cycle along the beachfront.
- Busselton Foreshore / Geographe Bay swim start — watch the mass swim start from the beach and cheer athletes out of the water into T1
- Busselton Jetty and foreshore promenade — the run course passes here multiple times on its multi-lap route, giving you several chances to cheer your athlete
- Finish line on the foreshore — the most emotional spot; arrive early to secure a good position for the final stretch
