"My understanding is that the storage requirements are for when it is at its "normal place of storage" for most days of the year. While you're travelling with your firearms they are not in "storage"
Thats my understanding for victoria. So you take other precautions.

Safekeeping of firearms when being transported in vehicles
The information below has been developed to provide firearm licence holders a guide on how firearms and ammunition should be transported in most circumstances.
While the guidelines are aimed at minimising risk, licence holders should consider all factors that may contribute to the firearms being transported in a manner that is not secure or in a way that presents a danger.
Police will treat each individual case on its merits and there may be circumstances where the guidelines are followed but criminal charges are still warranted if the overall security of the firearms are compromised due to aggravated circumstances.
For example if a firearm is securely stored in the trunk but the owner of the vehicle is driving the vehicle while intoxicated or speeding they might be considered to have compromised the security of the firearm. Additionally circumstances such as this may indicate that the firearm owner may not really understand the responsibilities required for proper firearm ownership.
In most circumstances firearms should be transported in the following manner:
Firearms should be transported in a padded cover or hard case, unloaded and preferably rendered inoperable;
While being transported, firearms and ammunition should be kept out of sight and stored in separate receptacles that are either secured to the inside of you vehicle or in a lockable component of your vehicle; and
Cartridge ammunition should be stored separately from the firearms in a part of the vehicle not readily accessible by an unauthorised person. A lockable glove box would suffice provided the key to the glove box is kept securely by the holder of the firearm licence and cannot be accessed by persons unauthorised to possess ammunition or firearms.
Licence holders should exercise a common sense approach to storage when transporting their firearms and be mindful of all of their obligations.
The advice above has been provided as a guide only and does not override storage requirements imposed by other regulatory frameworks. For example the storage requirements imposed under the Wildlife (Game) Regulations 2012 when hunting in a deer habitat.
NOTE: I understand that if the firearm is left alone with an unlicenced person in the car it would not be legal otherwise locked in the boot is ok. Trigger locks or locking the bolt in tbe ammo box might cover that situation, but not certain.
NOTE: Many regulations have areas that are "silent" and full compliance is very difficult to achieve. The firearms regs are no different in that regard. On some worksites/industries it can be a nightmare complying with the OHS requirements.
