Cycling helmets are a legal requirement in Australia. Any helmets sold into Australia must pass Australia regulations. Ensure that you helmet passes the Australian standard by purchasing locally. Helmets provide the obvious protection in the event of a crash. Whilst they can be used between the different cycling forms, there are some slight differences. Mountain bike helmets typically feature a visor and are harder wearing, like the Limar X-MTB, and road helmets tend to focus primarily on aerodynamics and weight, like the Limar 778 Helmet.
