IN BRIEFAustralians facing financial hardship are the most likely to change travel habits as fuel costs climb.Many Australians who switched transport modes during the fuel spike may not return to driving.Alana Cullen used to drive to work five days a week.But when petrol prices began climbing earlier this year, the Sydney office worker started looking for ways to reduce her weekly spending.Now, she walks part of the journey and catches a bus for the remainder of her commute."It wasn't really a choice for me," she told SBS News."With the cost of groceries, housing and pretty much everything else going up, fuel was one of the areas where I felt I could save a little bit of coin without too much effort."News that makes senseYour trusted source for staying up-to-date with the world around you.

Cutting back on that has given us a little bit of breathing room."Pearson said that those who were adapting the most are people who ‘experience financial disadvantage and younger people’."What that suggests is that it is not so much something that is particularly chosen or motivated around values around sustainability, but instead by forced adoption and a need to do due to costs."It tells us that those who have the ability to be able to be able to change to safe, affordable, reliable and active modes of transport are particularly those living in cities, often people who have good access to reliable public transport," she said.More Australians considering active alternativesThe report also found growing interest in more active forms of transport.Nearly two-thirds of respondents said they would consider walking more often, while more than a third were open to cycling and more than a quarter expressed interest in using e-bikes.Public transport usage also increased during the fuel price spike, particularly in Victoria, where the state government introduced free public transport in March as part of a broader cost-of-living relief package.The research found 45 per cent of Victorian respondents reported new or increased public transport use, compared with 25 per cent in Tasmania.In a statement to SBS News, Victorian Public and Active Transport Minister Gabrielle Williams said the fare relief measures were helping commuters manage rising transport costs while encouraging greater use of the network.Williams said the temporary measure was making "a real difference", saving commuters up to $456 across April and May, with half-price fares due to be introduced in June and remain in place until the end of the year.Researchers argue the findings should prompt governments to invest more heavily in public transport, walking and cycling infrastructure, particularly for communities facing cost-of-living pressures.Cullen said that while she misses the convenience of driving, there have been several unexpected benefits, as well as the obvious benefit of spending less money."It does take more organisation and planning, but I get more steps in every day, and I actually use the bus ride to get organised before work," she said."I'll check my emails, reply to messages from family and friends or just have a few minutes to myself before the day starts."It's not as simple as jumping in the car, and it does require a bit more planning for timing purposes, and a buffer for public transport delays, but there are definitely parts of it I've come to appreciate."Price hikes driving long-term changeThe study also estimates as many as one in three Australians who changed their travel habits during the fuel crisis may continue those behaviours even if petrol prices fall."Twenty-seven per cent of people said they would probably continue, 8 per cent definitely and 38 per cent of people were saying they were unsure.""People are potentially finding these ways to get around are not as reliable, safe, easy or viable within their every day…That’s why it is so important to consider how we can make these modes viable and enjoyable for people to use in the future," Pearson said.Experts say the findings raise broader questions about transport affordability, infrastructure investment and whether Australia's transport systems are equipped to support people seeking alternatives to driving."Transport and fuel costs were one of the major drivers of inflation in the recent couple of months… When prices are high people will seek alternatives so now is a better time than ever for governments to embrace investments in public transport," Thrower said.Even if petrol prices fall, Cullen said she is unlikely to return to driving every day, but values having the option when public transport doesn't fit her schedule or needs."I would like to drive a little more often, but now that I've adjusted to the commute I can see myself continuing to enjoy mixing things up rather than driving everywhere all the time," she said."But if public transport was a bit more frequent and reliable, I'd probably be less reluctant to fully make that switch, it's very frustrating when buses are late or don't come at all … And obviously, on days when it's raining, or I have a rigid schedule, it's impractical so I still have to drive."For the latest from SBS News, download our app and subscribe to our newsletter.
