A survey has found four in five Australians believe medicines are not subsidised by the federal government quickly enough after they are discovered.

Rare Cancers Australia chair Richard Vines said that he is aware that the Pharmaceutical Benefits Scheme is geared towards treating prominent conditions and some people are against getting treatment because of unaffordable prices.

Mr Vines agreesĀ in the delay of some medicines due to price negotiations and the process of designing a health system and said that they are finding ways to make this better and faster.
