Hiking Backpacks Australia – Day Packs, Ultralight & Adventure Packs
The right hiking backpack makes the difference between a great day on the trail and a miserable one. Too heavy and your shoulders ache by midday. Too small and you're rationing water. Too flimsy and it fails when you need it most. Our range of hiking backpacks covers everything from ultralight day packs for short walks to full-featured adventure packs for multi-day treks — all selected for real-world performance on Australian and international trails.
Travel Gear Australia ships fast from our Charlestown, NSW warehouse. Every hiking backpack in our range has been chosen for durability, comfort, and value.

What to Look for in a Hiking Backpack
-
Fit & torso length: The most important factor — a pack that fits your torso transfers weight to your hips correctly and prevents back pain
-
Hip belt: A padded, adjustable hip belt transfers 70–80% of the pack's weight off your shoulders — essential for packs over 20L
-
Back panel ventilation: Mesh back panels create airflow between the pack and your back — critical for warm Australian conditions
-
Hydration compatibility: Look for a hydration sleeve and hose port if you prefer a hydration bladder over water bottles
-
Weight: Ultralight packs (under 1kg) are ideal for day hikes; heavier packs with more structure suit multi-day loads
-
Rain cover: Many packs include a built-in rain cover — or pair with a dry sack for waterproofing valuables inside
-
Organisation: Hip belt pockets, top lid pockets, and front panel access make a big difference on the trail
Hiking Backpack Buying Guide
For Day Hikes
A 15–25L day pack is ideal. Look for a hydration sleeve, hip belt pockets for snacks and phone, and a lightweight build. The Sea to Summit daypack range is a standout for ultralight packable options that compress to almost nothing when not in use.
For Multi-Day Treks
A 45–65L pack with a structured frame, padded hip belt, and multiple access points is the right choice. Prioritise fit over features — a well-fitted pack with fewer features beats a feature-rich pack that doesn't fit.
For Travel + Hiking
A convertible travel backpack or lightweight travel backpack that doubles as a hiking pack is ideal for travellers who want one bag for airports and trails. Look for a lockable zip option if you're visiting high-risk destinations — or consider an anti-theft backpack for city travel.
Frequently Asked Questions
What size hiking backpack do I need for a day hike?
A 15–25L day pack is ideal for most day hikes. It fits water, snacks, a first aid kit, a rain layer, and a camera without being too bulky. For shorter walks, a 10–15L pack is sufficient.
What is the best hiking backpack brand in Australia?
Sea to Summit is one of the most trusted Australian hiking and outdoor brands, known for ultralight packable daypacks and adventure gear. Their packs are designed and tested for real-world conditions.
Can I use a hiking backpack as carry-on luggage?
Many day packs (15–25L) meet airline carry-on size requirements. Check individual product dimensions against your airline's limits. For a pack specifically designed for carry-on travel, see our carry-on approved backpacks.
Do I need a hydration bladder for hiking?
Not essential, but highly recommended for hikes over 2 hours. A hydration bladder lets you drink hands-free without stopping — particularly useful on steep or technical terrain.
