It appears you are correct.  Macadamia only have about 6 mcg of selenium per nut

Most sites about selenium list Brazil nuts as having a lot in them:

http://www.prevention.com/cooking/news/more/9606news4.html :
Brazil nuts have about 250
times more selenium than
most foods ... but only if you
buy 'em in the shell. Seems
Brazil nuts grow in two
regions of Brazil--a central region with selenium-rich
soil and a western region with far less. Fortunately,
exporters ship nuts form the central region with
shells on; nuts form the west come without shells. In
stores, Brazil nuts with shells have about 10 times
more selenium per nut--120 micrograms--than nuts
with the shells taken off.
