Love Luggage offers a massive range of luggage, backpacks, wallets and accessories online as well as in our Sydney based luggage Store in Newtown just a few Km from the CBD. For this post, I thought back to our years of traveling with a backpack and did a ton of recent research online via Google and digesting endless Amazon backpack reviews to come up with a shortlist of the best backpacks for travel to hopefully save you some time.
We can't resist but throw in one another Osprey pack for travellers and explorers looking for women-specific backpacks. Below, I've created a bit of a travel backpacks australia budget planning for you, based on the way I travelled myself in 2006: 3 months of backpacking Australia alone and 2008 (with my brother for 2 months).
For backpacking Western Australia, you don't really need a 4-wheel drive, only if you're planning to go onto the beach (tip: DON'T - you will get stuck and you won't be happy, like us, haha), the Pinnacles Dessert is fine with a normal car as are national parks like Karijini and Kalbarri Usally you park in the front and go further on foot.

If you go too big on size for your travel backpack, you'll have a tendency to fill the space and carrying too much gear around the world gets tiring real quick and is not good for the health of your back - we found ourselves de-cluttering and throwing away stuff we didn't need on a constant basis.
If your planning a longer trip and still wanting the convenience of a backpack a good choice may be the the Osprey Farpoint 55 travel backpack One of the advantages of this backpack is the detachable Daypack which can be easily removed and used as a carry on pack.
5. Maybe you could go with a smaller say 30L backpack as well as a lightweight shoulder strap duffle bag if 30L will not handle it all or even as suggested a smaller say 20L daypack, some people wearing them on their front with all their stuff wanted to be handier - Passp, camera, money, tissues, hand towell etc.
Most of the backpackers only travel the east coast on their first trip, but there's another side to this incredible country. Recognized as Australia's most famous city and the largest city in Oceania, Sydney is an effortless blend of beach culture and urban life.
