AUSTRALIA:
ACS members have been supplied with a letter from QANTAS verifying official permission to carry Li-Ion batteries with certain capacities on QANTAS Group flights.Camera crews are able to carry Li-Ion batteries of less than 100 Wh capacity in carry-on baggage only, provided the terminals are protected from short circuit.In addition to this, crews are allowed up to two batteries that have a capacity of between 100 and 160 Whs in their carry-on. In both cases, normal carry-on baggage weight limits apply.For further details, refer to the downloadable letter below. Please download and carry the attached letter from QANTAS at all times for confirmation to the airport staff.
