I fell for Kangaroo Island from my first visit. I recall standing on a headland on the island’s southern coast, near Remarkable Rocks (a popular tourist site), and being awestruck by the Southern Ocean.

The island (Australia’s third-largest after Tasmania and Melville Island) is one of 16 designated National Landscapes and arguably South Australia’s greatest tourism treasure. Its protected areas (notably Flinders Chase National Park) are home to rare and endangered marsupials and birds.

A year ago, in Australia’s “Black Summer”, bushfires ravaged more than half the island (about 211,000 hectares). Those fires underscored the threat to this and other iconic island destinations.

Both directly and indirectly, humans are endangering these fragile ecosystems through unsustainable development and human-caused climate change.

The most ironic threat is from unsustainable tourism. These islands attract millions of visitors a year keen to experience their natural wonders. Yet often this very “ecotourism” is contributing to their degradation.

How to do better?

Last October I took part in a workshop at which Kangaroo Island’s tourism operators discussed how to do so. 2020 was a difficult year for them, first with the fires, then with the COVID-19 pandemic. But in that adversity they also saw the opportunity to reset “business as usual” and come back better, creating an industry not harming its core asset.

A range of ideas came out of our talks applicable to all our island destinations. But there was one key point. Ecotourism should be more than fleeting feel-good experiences. It should not be a “value extraction” but a “values education”, inspiring visitors to go home and live more eco-consciously.

Macquarie island

The paradox of ecotourism is perhaps best exemplified by Australia’s least visited island destination – Macquarie Island, about 1,500 km south-east of Hobart, halfway between New Zealand and the Antarctica.

Just 1,500 tourists a year, rather than hundreds of thousands, are permitted by the Tasmania Parks and Wildlife Service to visit. The island has no hotels, restaurants or souvenir shops. The only buildings are those of the Macquarie Island Station research base and a few isolated field huts for scientists.

Tourists must be content with coming ashore for the day from the 18 small cruise ships that ply these waters in summer. The only hospitality is the traditional station offering of tea and scones.

But what tourists do get is a unique experience. Macquarie is World Heritage listed as the only island made entirely from the earth’s mantle. It also teems with wildlife – multiple species of penguins and seals in their tens of thousands, and birds in their millions.

It’s about as pure an ecotourism experience you can have (if you can afford it). Even so, it still takes resources to get there, including the burning of fossil fuels, contributing to the global warming that is the greatest threat to the environmental integrity of Macquarie Island (and other island ecosystems).

However, the Tasmania Parks and Wildlife Service does at least expect cruise ship operators to “demonstrate their capacity to deliver desirable outcomes” on criteria including minimisation of environmental impacts and communicating to tourists “messages about the natural and cultural values of the island”, including the role they play in its preservation.

K'gari (Fraser island)

Communicating such messages is something that certainly needs improvement on another World Heritage listed island – K'gari (commonly known as Fraser island), the world’s largest sand island.

About 250 km north of Brisbane, at the southern end of the Great Barrier Reef, the island draws many hundreds of thousands of visitors a year to its beaches, woodlands and rainforests. (There are no recent public statistics on island visitor numbers but in 2017-18 the Fraser Coast region attracted 1,515,000 visitors.)

Once the island’s resources were mined and logged. Tourism was meant to be much less exploitative. But a range of organisations including the International Union for Conservation of Nature have highlighted the pressure tourist numbers (along with their vehicles and infrastructure) are placing on K'gari’s landscapes and wildlife.

Communicating to all those visitors the role they play in the island’s preservation appears to be failing. The bushfires that burnt half the island (about 165,500 hectares) over nine weeks between October and December last year allegedly resulted from an illegal camp fire.

Headline-grabbing attacks by the island’s residents dingos – such as in April 2019 when a toddler was dragged from a campervan – have also been credited to rampant irresponsible tourist behaviour (feeding dingoes to get better photos, for example).

Indigenous elders, conservationists and scientists have all pointed to the problem of a mass-tourism model that doesn’t put enough emphasis on educating visitors about the environment and their responsibilities.

Rottnest Island

One of our proposals for Kangaroo Island is to reduce the impact of motor vehicles through encouraging more extended walking and cycling experiences.

The value of sustainable transport as the foundation for ecotourism is demonstrated by Rottnest Island, 20 km off the coast of Perth.

The entire island is managed as an A-Class Nature Reserve. Apart from service vehicles and shuttle buses, it is car-free. You can hire a bike or bring your own to get around the island (11 km long and 4.5 km wide). Or simply walk.

The absence of traffic makes a Rottnest holiday a distinctly more relaxed experience. It’s a fair example of slow tourism; and, of course, it is also good for the island’s world famous quokkas, which co-exist with close to 800,000 visitors a year.

Before they are gone

Given a little space, nature is resilient.

After Kangaroo Island’s bushfires a year ago, for example, it was feared a number of endangered species had finally been driven to extinction.

But in two of 2020’s few good news stories, scientists found critically endangered Kangaroo Island dunnarts and little pygmy possums – the world’s smallest marsupial – had survived.

But we can’t take that resilience for granted if we keep putting pressure on these fragile ecosystems. We need a better approach to ensure ecotourism isn’t about enjoying these natural wonders before they are gone.
