Carry-On Size Guide: Every Australian Airline (2026)

Australian airlines publish different carry-on rules, and they change them. Virgin Australia adjusted its economy allowance during 2026, and Jetstar and Qantas both moved baggage pricing in January. Everything below reflects what each airline published at the time of writing, and we update this page as the rules move. Confirm the figures on your airline's own site before you fly, because the version that counts is the one printed on your booking.

Australian Domestic Airline Carry-On Size and Weight Limits

Two things to note from the table.

The Australian hand luggage size limit barely differs. Qantas, Jetstar and Virgin all settle on 56 x 36 x 23cm, so a bag that fits one fits all three. Rex is the exception at 48 x 34 x 23cm, which rules out a standard cabin roller on regional services.

The weight limit moves a lot. Ten kilograms on Qantas, eight on Virgin, seven on Jetstar and Rex. That gap decides which bag you should buy far more than dimensions do.

Qantas also runs a tighter rule on QantasLink Dash 8 turboprop services, which drop to 7kg with smaller dimensions. Regional routes on any airline deserve a check rather than an assumption.

International Carry-On Limits for Australian Airlines

International rules diverge from domestic ones, and the difference catches people out on the way home from a domestic connection.

Qantas international economy allows one bag with total dimensions up to 115cm, which is the same 56 x 36 x 23cm shape, capped at 7kg. Premium Economy, Business and First lift that to 10kg, or two bags within 105cm each totalling 14kg. The headline point is the drop from 10kg domestic to 7kg international in economy.

Virgin Australia applies the same carry-on allowance internationally as it does at home, so 8kg in Economy with the 56 x 36 x 23cm shape.

Jetstar also runs identical carry-on rules across domestic and international routes at 7kg combined.

If your trip mixes a domestic leg with an international one, pack to the lowest allowance in the itinerary. Qantas states this directly, and gate staff apply it.

What Counts as a Personal Item Rather Than Carry-On

Every Australian carrier lets you bring a second, smaller item into the cabin. The definitions differ enough to cause arguments at the gate.

A personal item goes under the seat in front of you. A handbag, a slim laptop bag, a small backpack, a camera. Virgin Australia publishes exact dimensions at 45 x 33 x 20cm, which is the clearest figure in the market. Qantas and Jetstar describe it by function rather than measurement, which sounds generous until someone at the gate decides your 30-litre backpack is a second cabin bag.

Here is where it trips people up. On Jetstar and Rex, the personal item counts inside the total weight allowance. Seven kilograms covers both bags together, not each. A 2kg laptop bag leaves you 5kg for everything else. On Virgin, the 8kg applies to the main bag, with the personal item allowed separately.

The practical version. Assume your personal item must fit under a seat, assume its weight counts unless the airline says otherwise, and pick a daypack around 20 litres rather than 30.

How to Choose a Carry-On That Fits Across Airlines

Buy for the strictest limit you will realistically fly, not the most generous one.

Size is the easy part. A bag at 56 x 36 x 23cm clears Qantas, Jetstar and Virgin. Buy at that dimension and stop thinking about it. Only add a check if you fly Rex or regional turboprops.

Weight is where the decision actually happens. A hard-shell cabin case with four wheels typically weighs 3.4kg to 3.7kg before you put anything in it. Under a Jetstar or Rex 7kg allowance, that leaves roughly 3.3kg for clothes, which is a long weekend at most. Under a Qantas domestic 10kg allowance, the same case leaves 6.3kg and works comfortably.

So the honest advice runs like this. Fly Qantas domestic often and a wheeled case is a good buy. Fly Jetstar, Rex or Qantas international economy often and a soft bag or a travel backpack gives you far more usable weight, because the bag itself weighs one to one and a half kilograms rather than nearly four.

Check the empty weight before the feature list. It is the number that decides how much you can actually take. Empty weights across the carry-on bags range vary by more than two kilograms between models, which is a third of a Jetstar allowance.

Watch expansion zips. A 5cm expansion is useful on the way home. It also pushes the bag past the Australian hand luggage size limit, and several manufacturers say so in the fine print. The Renegade Vault Carry-On Bag adds 5 litres when expanded and notes that the expanded size may exceed overhead bin limits, which is the kind of disclosure worth looking for.

Match wheels to your route. Four spinner wheels move easily through a terminal and roll upright beside you. Two inline wheels handle cobblestones and kerbs better and usually weigh less. The Renegade 4-Wheel Carry-On Bag sits at 3.4kg with four wheels, which is light for its category.
