If you are traveling to Perisher Resort in a two-wheel drive car you are required to carry chains in your vehicle between Jindabyne & Perisher. If traveling to Thredbo they are not compulsory, however it is recommended. Four-wheel drive and all-wheel drive vehicles are not required to carry chains.
It is helpful to know how to fit the chains or get a demonstration before you head to the mountain. In peak periods there may be a chain fitting service available on route to the mountain, however it is not guaranteed.
