Victoria’s Great Ocean Road clocked up a century on Thursday, but the world famous tourist drive is fighting for survival amid dual threats of climate change and over-popularity.
Famous for its limestone cliffs, surf breaks and rainforests, the 242km route is close to “being loved to death,” locals say.
“It’s becoming a bit of a gridlock,” said an Apollo Bay surfer and fisherman, Peter Fillmore, who has lived in the region for 40 years.

Traffic congestion has ramped up in the past decade, fueled by a boom in Chinese tourists on coach tours and independent driving trips.
The road was driven on by 6.1 million international and domestic tourists who spent US$1.4 billion in the year ending in March.
However, some locals lament that many day trippers come for a quick selfie and then return to the city and do not spend much money in towns along the way.
“What we would like to see is fewer tourists, but spending longer here, exploring the other wonders that the area has to offer,” Aireys Inlet and District Association president Charlotte Allen said.
There have also been safety concerns raised about international drivers after multiple fatal road smashes.
“One of the real pressure point places is at the memorial arch. Parking is limited, and there are no toilet facilities. All the big buses leave Melbourne at the same time, and they all want to stop at the memorial arch to get a photo. It just becomes absolutely crazy with people standing in the middle of the road and people using the bushes for toilets. It’s a nightmare,” Allen said.
Her association has called on authorities to undertake a study to determine whether the region’s peak tourism capacity has been reached and consider measures such as tolls to limit numbers.
Fillmore said the road is no longer fit to cope with today’s traffic.
“When they built the road they probably didn’t put a lot of base material on it, thinking that it was just going to be for Model T Fords and horse and carts,” he said.
Although federal and state governments have spent US$150 million in recent years fixing landslips, Fillmore believes tourists should be helping to maintain the road.
“You’re passing through a national park to get here. Virtually everywhere else in the world where you enter a very popular national park you pay a fee. Every tourist who comes down that road should be paying at least $20,” he said.
He said a ban or limit on the big 50- to 60-seat coach buses should be considered.
“The really big buses weigh a lot and you can see they’re damaging the road,” he added.
Victoria’s southwest coast has always been a treacherous part of the world. More than 200 shipwrecks lie off the coast.
In 1802 the explorer Matthew Flinders said he had “seldom seen a more fearful section of coastline,” and the climate emergency has the potential to make conditions even rougher.
A University of Melbourne ocean engineering expert, Ian Young, said that by 2050 the average sea level rise could be 60cm along Victoria’s southwest coast.
“Our work shows by 2100 you can expect extreme storm waves in the Southern Ocean to increase [in height] by between 10 and 15 percent,” he said.
Asked if this could mean the loss of more of the 12 Apostles, Young said: “It’s quite possible there could be some more natural erosion of those sorts of coastal features, yes.”
Young said low pressure systems that come across the Southern Ocean are intensifying, and this has implications for tides and sand dunes.
“The winds are getting stronger and that accounts for the higher wave conditions, and also those low pressure systems are tracking further to the south and what that does is it means the waves will come from a slightly more southerly direction,” he said.
“If the wave direction changes you’ll see a change in orientation of the coastline as well. If you have a long beach and the wave conditions change two or three degrees then the alignment of the beach will change. This may not seem like much, but the change in orientation of the coastline will cause erosion in some parts of the beaches,” he said.
Young said a lack of data makes it difficult to know whether storm surges will increase on the Victorian southwest coast.
Geomorphologist Neville Rosengren and geotechnical engineer Tony Miner looked at erosion around the Apollo Bay and Mounts Bay areas over the past two years for an independent report released in October last year.
They warned the state government that “the Great Ocean Road could potentially be compromised in less than a decade and possibly within five years.”
At beaches along the Great Ocean Road there are scores of shell middens which, in some cases, date back 5,000 years.
These Aboriginal cultural heritage sites mark where Indigenous people could cook and eat abalone, periwinkle sea snails, mussels and spoon fish shells. Ancient tools have also been found, but the sites are starting to wash away.
Guli-Gad elder Ron Arnold said dozens of middens have already been destroyed and damaged.
“We can’t protect all of them. There are some that are a little more inaccessible. There are certain ones that could be highlighted for tourism and education. They’re the ones that we’re looking to protect and preserve for the future,” he said.
The Great Ocean Road did not have government support when construction began in 1919.
The concept was the brainchild of the then-Geelong mayor, Howard Hitchcock, and Victorian residents funded it themselves through tolls to help create jobs for veterans returning from World War I.
A member of the Lorne historical society, Peter Spring, said 3,000 returned servicemen worked on the most difficult stretch from Eastern View to Apollo Bay, which winds around cliffs. The men were hanging by ropes using picks and shovels to cut into the cliffs.
“There were no explosives used in the first few years, mainly because a lot of the servicemen returning from war were suffering from shell shock. It was hard work done by hand,” Spring said.
The men worked in grueling cold, windy and soggy conditions.
“In fact there’s one section of the road at the start of the climb at the Otway Ranges which they referred to as the Somme, named after the battlefield in western France where the conditions were appalling,” Spring said.
Remarkably, there were no casualties in the construction, which was completed in 1932.
The Victorian government released an action plan in October last year. It is also establishing an independent authority to preserve the road and coastal environment.
Victorian Minister for Roads Jaala Pulford said modern technology helps engineers monitor conditions.
“Drone surveying has allowed geotechnical engineers to model the terrain above and below the road, capturing steep cliff faces, historical landslip sites and areas previously inaccessible to surveyors,” she said.
“Rock armor walls are being constructed beneath the road and along the foreshore to help protect the road from the impacts of coastal erosion, while high-tech weather stations are providing rainfall and soil moisture content data to help engineers measure the impacts of these factors on the cliff faces above and below the road,” she added.
Pulford said rock netting, soil nailing and erosion control matting are also being rolled out to stabilize the embankments to help prevent loose rockfall.
The Great Ocean Road has a special place in the heart of 2011 Tour de France champion Cadel Evans, who has a home at Barwon Heads, near Geelong.
Despite riding professionally all over the world, Evans said the Great Ocean Road is one of his favorite cycling routes.
“It is so spectacular. You don’t realize how good this country is until you live overseas — the smell of the eucalypts, the clear skies, the people are friendly and when the sun is shining, it is just beautiful,” he told Jetstar travel magazine earlier this year.
Saudi Arabian largesse is flooding Egypt’s cultural scene, but the reception is mixed. Some welcome new “cooperation” between two regional powerhouses, while others fear a hostile takeover by Riyadh. In Cairo, historically the cultural capital of the Arab world, Egyptian Minister of Culture Nevine al-Kilany recently hosted Saudi Arabian General Entertainment Authority chairman Turki al-Sheikh. The deep-pocketed al-Sheikh has emerged as a Medici-like patron for Egypt’s cultural elite, courted by Cairo’s top talent to produce a slew of forthcoming films. A new three-way agreement between al-Sheikh, Kilany and United Media Services — a multi-media conglomerate linked to state intelligence that owns much of
The US and other countries should take concrete steps to confront the threats from Beijing to avoid war, US Representative Mario Diaz-Balart said in an interview with Voice of America on March 13. The US should use “every diplomatic economic tool at our disposal to treat China as what it is... to avoid war,” Diaz-Balart said. Giving an example of what the US could do, he said that it has to be more aggressive in its military sales to Taiwan. Actions by cross-party US lawmakers in the past few years such as meeting with Taiwanese officials in Washington and Taipei, and
Denmark’s “one China” policy more and more resembles Beijing’s “one China” principle. At least, this is how things appear. In recent interactions with the Danish state, such as applying for residency permits, a Taiwanese’s nationality would be listed as “China.” That designation occurs for a Taiwanese student coming to Denmark or a Danish citizen arriving in Denmark with, for example, their Taiwanese partner. Details of this were published on Sunday in an article in the Danish daily Berlingske written by Alexander Sjoberg and Tobias Reinwald. The pretext for this new practice is that Denmark does not recognize Taiwan as a state under
The Republic of China (ROC) on Taiwan has no official diplomatic allies in the EU. With the exception of the Vatican, it has no official allies in Europe at all. This does not prevent the ROC — Taiwan — from having close relations with EU member states and other European countries. The exact nature of the relationship does bear revisiting, if only to clarify what is a very complicated and sensitive idea, the details of which leave considerable room for misunderstanding, misrepresentation and disagreement. Only this week, President Tsai Ing-wen (蔡英文) received members of the European Parliament’s Delegation for Relations
