CC - you might be best placed to help me with sizing advice here, but others views welcome too

I am a Australian size 12 (well probably a 14 at the moment but I'm hoping thats just winter weight) and a NZ bra size 14 D (for all you other ladies thats 5'2", 130 ish pounds and a 36 D bra - I have no idea how your american sizes work) - I'm thinking I might need a large in the womens club cut - what do you think?

I thought about getting one last year but it was just a bit pricey - with the NZ dollar at an all time high against the USD now I have less reasons for putting it off
