GULF TO GULF

30 days to ride the 'G2G' across Australia, taking the remote outback route from Port Augusta via Marree, Birdsville and Cloncurry to Karumba.

NORTHBOUND

Riding Tue 29 May to 27 June 2027

17.07.25: 2026 G2G has been postponed

Transfers are from Adelaide to Port Augusta and from Karumba on to Cairns.

Join one of Australia's great bike challenges, tracing a trail Gulf-to-Gulf across the heart of our amazing continent.

These ancient lands reflect the heritage of Australia's First Peoples who lived out there admirably well - and the courage, tragedies and successes of European explorers like the famed but unfortunate Burke and Wills - and the settlers who forged their existence in what was, for them, a land of unforgiving remoteness. 

The ride has 4 stages, each about a week: 

Week One explores the majestic Flinders Ranges, riding from Port Augusta 430km to reach the desert railhead of Marree in 6 days (7th day is rest).
Week Two traverses the legendary Birdsville Track, 520km of gravel in 8 days including a rest day at Mungerannie.
Week Three rolls 720km across Queensland's vast Channel Country to Cloncurry in 8 days. Rest days in Boulia and Cloncurry (with optional bus trip to Mt Isa).
Week Four rides 450km in 5 days through the Gulf Country to Normanton and Karumba (followed by end-of-ride rest day).

The most recent rides took place in May-June and June-July 2022, May-June 2024 and May-June 2025, all with 20-24 riders. Ages ranged from 30s to 70s with the median age in the early-60s. 

2027 COST:

$9000 - Full ride including transfers from Adelaide and to Cairns, support services, 33 nights camping and most meals.

Outbike's first G2G event was in 2005.

THE RIDE IN BRIEF

Riders transfer from Adelaide on our bus on the day prior.

In 2005, 2006, 2007, 2008, 2010, 2016, 2019, 2022 (2 rides), 2024 and 2025, riders set forth from SA's Port Augusta to ride ~2200kms to eventually reach Karumba, Queensland - crossing the continent on the way.

In 2027, we'll ride from Port Augusta again.

Maximum 25 riders (minimum 15). We will 'overbook' to 27-28 riders to allow for withdrawals.
Staff of 3-4 plus helpers to give a high level of service together with 3 or 4 support vehicles.

You need to be ready to cycle days of 80km on dirt roads (dirt is about 670km, most of this is the Birdsville Track) of varying surfaces! On the sealed roads (about 1400km), the longest days are 100-120km. About 400km has been sealed since 2005.

The 2027 ride is 30 days including 5 rest days. Transfers and a Karumba rest day makes it all 34 days. We include 33 nights camping (11 at bush sites), daily hearty breakfasts, lunches on ride days, dinners on remote camping nights plus Wilpena and Angorichina (local pubs the rest at own cost), extensive rider support and transfers on our bus from Adelaide and afterwards to Cairns.

We've talked on the rides about ideas for faster and slower versions of this event to suit different rider abilities - but the 30 days seems to work well for a range of abilities and gives us some flexibility for weather events that we can't predict.

In 2016, 60mm of rain hit Birdsville after we arrived and delayed us for the rest day and 4 more days. We were glad to be in town and not trapped on the track! Back on the road, some 100km days became 150km or even 200km and many riders still made it the whole way.

In 2019, floodwaters from summer monsoon rains in NW Qld closed the upper part of the Birdsville Track (4 days of the ride) from Feb to Jun. It didn't reopen in time for us so we bused back from Mungerannie to Lyndhurst and detoured, driving via the Strzelecki Track and Innamincka to Birdsville. This slow, rough and dusty bus trip took 5 days (over 1000km) but the ride was back on schedule.

In 2022 the Birdsville Track had been closed but opened in time as the Northbound ride approached. Then upon leaving Birdsville, new floodwater closed the bridge behind us same day, not to reopen until a week into the Southbound ride. 

In 2024 again the Birdsville Track had been closed for months. Over the years, we've pushed back the start from late-April to mid-May to allow late-summer floodwater to drain. Incredibly, a weather front and rain coincided with our arrival to Birdsville and the Track closed behind us. This time 26mm of unseasonal rain fell Fri-Sat into our rest day but by Noon Monday the road north opened and we still made Boulia comfortably in 4 days (having also to detour on the gravel around Lake Machatie).

In March-April 2025 inland Queensland was inundated by record flooding. The Birdsville Track closed and we've heard it may reopen in August! The G2G rode up as far as Mungerannie, packed up and shifted over to ride parts of the Oodnadatta Track before most riders took a scenic flight to Birdsville and others journeyed around with the vehicles via Broken Hill and Quilpie. 

Next ride is now starting Tue 29 May 2027, riding from Port Augusta. Transfers from Adelaide on 28 May.

ABC INTERVIEW NEARLY HALF-WAY

"It's something I’ve dreamt about for many years, actually I never thought I’d be on the Birdsville track, and here I am on a bicycle, and we’re only about 80 kilometres from Birdsville now, and its been absolutely marvellous, its been difficult, hard, the flies have made it worse of course, and the sand and the dust". 

Helmut Gebels speaking to ABC Radio, Birdsville Track Inside Route, May 2005
