The Queensland Museum is hosting an exhibition
"Hadron Collider: step inside the world’s greatest experiment" from 9 December to 25 April, on tour from the Science Museum in London.

The award winning exhibition recreates the largest scientific experiment ever constructed - I'm not sure how they fit it inside the Queensland Museum building?
(Maybe all the tunnels that have been developed under Brisbane recently have just been preparation for the exhibition?
)
I've got a friend who works at the Museum, and she says it is the best exhibition at QM that she has seen to date. Note that they have a few "UpLate" sessions (Friday nights: 9 December 2016, 3 February & 3 March 2017), which have talks and entertainment, and probably give you the opportunity to see the exhibition with slightly smaller crowds than the normal opening hours.
