For those who celebrate, Australia Day signals long, sun-soaked fiestas filled with barbecues, beach trips, and, of course, bubbly social drinks. But, research from YouGov reveals a surprising truth – millions of Aussies are starting the day dehydrated, even before festivities begin. In fact, four in five Australians (80%, or 17.4 million people) aren’t meeting their daily fluid intake, raising concerns for a day defined by heat, food, and alcohol.
State-by-state figures show just how widespread the issue is. Victoria leads the pack for dehydration, with 87% of adults (around 4.8 million people) not drinking enough fluids. New South Wales and South Australia aren’t far behind, each with 81% of adults falling short. Queensland sees 77% of adults (around 3.4 million) dehydrated, while Western Australia fares slightly better. Yet 71% of adults still aren’t adequately hydrated.
These numbers underscore why Australia Day can be a risky time for our bodies. Research also highlights worrying habits: one in seven Australians rely on coffee to relieve dehydration symptoms, men are nearly twice as likely as women to be unaware of recommended daily fluid intake, and younger generations are more likely to supplement with electrolytes – Gen Z nearly twice as often as Baby Boomers (49% vs 24%). Clearly, hydration is a daily struggle, but even more crucial on a day when long hours, heat, and celebratory drinks collide.
St John Ambulance Australia offers practical tips to help Australians stay hydrated. And, crucially, avoid dehydration-related fatigue, dizziness, or headaches.
1. Drink regularly, don’t just when thirsty
Prevention is better than treatment. It’s easy to assume thirst signals the need for fluids, but by the time you feel thirsty, your body is already experiencing mild dehydration. Make it a habit to sip water consistently throughout the day, from breakfast to bedtime. Consider carrying a refillable bottle and setting reminders if you tend to forget, and don’t wait for cues like headaches or dry lips to hydrate.
2. Limit dehydrating drinks
Alcohol and caffeine may be party staples, but both can contribute to dehydration. If you’re planning on enjoying a few drinks with friends, balance each alcoholic beverage with a glass of water. Coffee is fine in moderation, but relying on it to combat dehydration can backfire. Think of hydrating drinks as your foundation – the celebratory drinks are just a garnish.
3. Eat your hydration
Hydration isn’t just about liquids. Many fruits and vegetables, like watermelon, cucumber, oranges, and tomatoes, have high water content and can complement your fluid intake. Snacks like fresh fruit skewers or crisp vegetable sticks are not only refreshing in the summer heat but also help maintain fluid balance throughout the day.
4. Listen to your body
Early signs of dehydration can be subtle – dry lips, dark urine, lightheadedness, or fatigue. Pay attention to these signals, particularly if you’re outdoors for long periods. Adjust your fluid intake proactively instead of waiting for symptoms to escalate.
5. Consider electrolytes
Finally, for longer days outdoors, especially in the heat or while engaging in physical activity, plain water may not be enough. Electrolyte drinks (Hydralyte do some excellent ice block varieties) can help replace salts lost through sweat and keep your body functioning optimally. Generational trends show younger Australians are already embracing this tip, but it’s beneficial for all ages.
By thinking ahead and making hydration a priority, Australia Day can be celebrated safely and energetically. Small adjustments – sipping water throughout the day, pairing drinks with hydrating foods, and watching for early warning signs – can make a huge difference in how you feel.
Whether you’re heading to a backyard barbecue, a beach day, or a picnic in the park, taking care of your hydration ensures you can enjoy every moment of the celebration. After all, a well-hydrated Australia Day isn’t just healthier—it’s happier, too.
