I, as an American English speaker, have the intuition that "right" could mean "very" in some British or Australian dialects. However, I could not find much information outside of a couple of dictionary entries that simply list it as dialectical or archaic usage.
For example, the entry from the free online Oxford Dictionary does indeed identify this usage of "right" as archaic and dialectical usage, though the entry in Merriam Webster's online dictionary provides this usage with no qualifiers. Meanwhile, the entry in dictionary.com provides no indication of that usage whatsoever.
