It takes years to plan a dream holiday, but just seconds for a government update to completely upend it.
For millions of Australians, Smartraveller is the ultimate oracle of overseas safety. Managed by the Department of Foreign Affairs and Trade (DFAT) across 179 destinations, its four-tier, colour-coded system does a lot more than just offer friendly travel advice.
It also dictates whether travel insurers will cover you. Go to a Level 4 "Do Not Travel" zone, and you're entirely on your own.
In the last financial year alone, DFAT quietly dropped a staggering 1148 travel advice updates. But as global conflict reshapes traditional tourist hotspots, it's important to know where Smartraveller warnings come from - and how they keep us safe.
Inside the colour-coded system
DFAT's updates offer general advice to assist Australians to make informed decisions about their safety and security when overseas.
There are four travel advice levels: Level 1 - Exercise normal safety precautions (Green); Level 2 - Exercise a high degree of caution (Yellow); Level 3 - Reconsider your need to travel (Orange); and Level 4 - Do not travel (Red).
The advisories are reviewed annually or biannually as part of a scheduled review process, and ad hoc travel advice is published for any new and significant information.
Each advisory has information about safety, health, local laws, travel and local contacts, and DFAT draws on a range of sources. These include Australian diplomatic missions overseas, threat assessments from ASIO's National Threat Assessment Centre, intelligence reporting, and information from consular partners in other countries. Media reports and feedback from travellers are also taken into account.
Rising risks and the reality on the ground
Travellers are possibly paying more attention to travel ratings now than ever before, says Daniel Gschwind, professor of practice at the Griffith Institute for Tourism.
"Given the current level of global safety and security concerns, travel ratings are likely to be taken more seriously by Australian travellers," he tells Explore.
Gschwind says "an increased risk-awareness has emerged" for people heading to the Middle East, where many holiday spots and transit ports were traditionally considered to be safe.
But communicating risks and potential threats in a manner that is easily interpreted by the general public is not an easy task.
For example, the current advice for the UK states: "We continue to advise exercise a high degree of caution in the UK due to the threat of terrorism."
What conclusion should a traveller draw from that and how should they adjust their plans? There are usually more explanatory notes included in the warning there can also be uncertainty about how to proceed.
"It is reasonable to assume that governments also issue travel warning to avoid potential future accusations of not providing adequate information if something does go wrong," Gschwind says.
So should travellers pay attention to this advice? It's a hard yes from Gschwind.
"Being well informed and preparing for potential disruptions or risks should be part of all travel planning. It is common sense," he says.
The limiting lag in data
One of the challenges setting travel advisories is they may naturally lag the events that influence their shape, says Joseph Cheer, professor of sustainable tourism and heritage at Western Sydney University.
"For example, in the case of social and political upheaval in the destination, advisories come out in response to an event not necessarily in advance of it," he tells Explore.
Cheer continues: "If the lag is too wide between the occurrence of an event and the release of the travel advisory, this could be futile because the risk factors may no longer be prominent."
Travel advisories can also be too heavily influenced by popular media commentary, and "not the actuality of what is going on the ground", Cheer says.
Travel insurance no-go zones
Travel insurance hangs on Smartraveller advisories. In an article recently published by Explore on the travel situation in the Middle East, TravelInsurance.com.au CEO Shaun McGowan says DFAT advice dictates whether their organisation will insure a traveller.
"What matters under our policy is whether a destination is at 'do not travel'," he says.
"We exclude loss from travelling to, planning to travel to or choosing to remain in a country or region where DFAT issued 'do not travel' advice before your arrival."
