Best Carry-On Luggage for Australians: Soft vs Hard & Does Size Matter?

What Size Is Carry-On Luggage in Australia?

There isn't one universal carry-on allowance across every Australian airline, but 56 × 36 × 23cm is an important benchmark. That adds up to 115cm linear, calculated by adding the height, width and depth of the bag.

Importantly, airlines measure the external dimensions of your packed bag, including wheels and handles where applicable. A bag that fits the dimensions when empty can exceed the limit once it is packed or expanded.

Airline baggage policies can change, so use these figures as a guide rather than a guarantee. Always check the baggage allowance attached to your booking before leaving home.

For current airline information, see Qantas carry-on baggage , Virgin Australia carry-on baggage and Jetstar carry-on baggage .

Does Size Really Matter?

Yes - but the largest possible bag isn't necessarily the best carry-on bag.

A bag that is technically within an airline's maximum dimensions can still be inconvenient if it is heavy when empty, difficult to lift into an overhead locker or awkward to carry through an airport.

For carry-on travel, look for a balance between:

• External dimensions that suit the airline you're flying with.
• Low empty weight so more of your allowance is available for your gear.
• Useful internal capacity rather than space taken up by unnecessary structure.
• Easy access so you can find what you need quickly.
• Comfortable carrying options when moving through airports and stations.

Soft vs Hard-Shell Carry-On Luggage

So which is better - soft-sided luggage or a hard-shell suitcase? The honest answer is that it depends on how you travel.

Why do we like soft-sided carry-on bags?

At Caribee, we have always valued the versatility of soft-sided travel bags. A fabric carry-on can be designed to do more than simply sit on four wheels. It can provide external access, flexible storage and, in many cases, multiple ways to carry the bag.

That's particularly useful when you're moving between airports, trains, hotels and city streets. Sometimes you want to carry your bag on your back, sometimes over your shoulder and sometimes simply roll it behind you.

For travellers who value this flexibility, the Caribee Traveller 40 combines a 40L capacity with concealed padded backpack straps, a split-level packing system, laptop protection and a luggage pass-through.

Why Empty Weight Matters

When an airline gives you a weight allowance, every kilogram of the bag itself reduces the amount you can put inside it.

That's one reason lightweight soft-sided carry-on bags can be attractive. The Traveller 40 weighs approximately 1.3kg, leaving more of your airline allowance available for clothing, electronics and other travel essentials.

The important thing is to consider the total packed weight, not simply the capacity printed on the bag.

What Is the Weight Limit for Carry-On Luggage in Australia?

There is no single Australian carry-on weight limit. The allowance depends on the airline, route, cabin and fare.

For example, Qantas currently allows up to 14kg across domestic Economy and Business carry-on, with a maximum of 10kg for an individual item. Qantas International Economy has a 7kg maximum. Virgin Australia's standard Economy allowance is 8kg, while Jetstar's current standard model uses a 7kg combined allowance across two items on applicable flights. 

This is why it's important not to rely on general airport advice such as "if you can lift it into the overhead locker, it's fine." Airlines can check both the size and weight of your carry-on and may require an oversized or overweight bag to be checked in. 

Backpack or Wheel Aboard Carry-On?

This is another important choice. Both styles can work well, but they suit different travel patterns.

Caribee's Adventure 40 Carry-On Hybrid is a good example of the hybrid approach. It combines a 40L capacity with a lightweight aluminium trolley system and concealed padded backpack harness, allowing you to roll through the airport and carry the bag when the terrain changes.

For a more traditional carry-on backpack, the Traveller 40 provides a lightweight backpack format with organised packing and a concealed harness.

What Makes a Good Carry-On Bag?

Beyond size and weight, there are several features that can make a noticeable difference to the way you travel.

What Is the Best Carry-On Luggage?

There isn't one best carry-on bag for every traveller. The right choice depends on what you carry, how often you fly and how you move once you arrive.

If you're travelling light for a weekend or business trip, a compact carry-on backpack may be the most practical option. If you're carrying heavier gear or moving between airports and hotels, a wheel aboard hybrid can reduce the amount of time you spend carrying the load.

The current Caribee Carry-On Backpack and Wheel Aboard collection includes lightweight carry-on backpacks, hybrid wheeled bags and cabin-friendly travel designs across a range of capacities and price points.

What Is Not Allowed in Carry-On Luggage?

Carry-on baggage is subject to Australian aviation security and dangerous goods rules. The restrictions cover more than just the size of your bag.

Items such as weapons, certain tools, sharp objects and other prohibited items cannot be taken through Australian airport security. Dangerous goods such as some flammable, explosive or hazardous substances are also subject to restrictions. 

Power banks and spare batteries should not simply be treated as prohibited items. They have specific aviation rules and should generally be carried in the cabin rather than packed in checked baggage. Always check the current airline and CASA requirements for your particular battery or device.

Liquids, aerosols and gels

For international flights departing Australia, liquids, aerosols and gels must generally be in containers of 100ml or 100g or less and fit within one transparent resealable plastic bag per passenger. These restrictions also apply to domestic legs departing from an Australian international terminal. They generally do not apply to most purely domestic flights. 

If you're unsure whether an item can travel in your carry-on, check with your airline and Australian airport security before you travel. Screening officers have the final say at the security checkpoint. 

What About International Carry-On Luggage?

If you're travelling overseas from Australia, don't assume that the Australian domestic rules will apply to every flight on your itinerary. Different airlines and aircraft can have different cabin baggage limits.

The safest approach is to check every airline on your itinerary and pack to the most restrictive size and weight allowance.

For example, Qantas currently lists 56 × 36 × 23cm as its overhead bag size, but its international Economy weight allowance is 7kg. 

If you're connecting through another country, also check the security and transit requirements that apply at that airport.

Carry-On Travel Tips for Australians

1. Check your airline before you pack Confirm the dimensions, weight allowance, number of bags and fare-specific rules for your actual flight.
2. Measure the packed bag Don't rely solely on the manufacturer's stated dimensions if the bag has an expansion section or becomes bulky when fully packed.
3. Weigh your bag at home A small luggage scale can save you from an unpleasant surprise at check-in or the gate.
4. Keep heavy items low and central This can make a backpack more comfortable and prevent the load from becoming unstable.
5. Keep essentials accessible Store passports, electronics, chargers, medication and other frequently used items where you can reach them easily.
6. Pack liquids correctly If you're flying internationally, prepare your liquids, aerosols and gels before reaching airport security.
7. Don't overpack simply because you have space A lighter carry-on is usually easier to lift, carry and move through busy airports.

So, Soft or Hard?

For many Australian travellers, we think soft-sided carry-on luggage offers an excellent combination of low weight, flexibility, accessibility and versatile carrying options.

A hard-shell suitcase still makes sense if rigid protection is your priority or you prefer a traditional suitcase packing system. But if you regularly move between airports, trains, hotels and city streets, a soft-sided backpack or hybrid wheel aboard bag can give you more ways to carry your luggage.

Ultimately, the best carry-on isn't simply the biggest bag that fits inside the airline's measuring frame. It's the bag that gives you the right combination of capacity, weight, organisation, comfort and mobility for the way you actually travel.
