Shameless plug for the KeNalu paddles, just heat them up with a hair dryer, take off the handle and the blade and then all you check is the shaft in a cardboard or pvc pipe tube. At the other end just heat them up again and put them back together, takes 5 minutes.
you must still end up with a 1.5 -1.6 metre long shaft and if that is deemed too long you will not be allowed to take it , ps If a hairdryer can soften the hot glue then be carefull of the Aussie sunlight in a car or on the sand too.
