If you like nature and you cannot afford to visit Africa or South America then this is the place for you. Since I move about the globe a lot I thought I had seen everything before. Firstly, the content is focused on the general public and school children so the science is sometimes weak. But they at least try and communicate the facts to you in an interesting way. I generally ignored the butterfly room since I had to pay to see butterflies, if this is your thing a visit to Sydney would do you wonders and it is free and much larger. The fossils were stunning and the geological section (I am a bit biased here) was as good as I have ever seen with good layout. The specimens were great and they covered the different topics of gems, crystals and minerals in a sensible but fun way. There is also a totally revamped shop at the bottom floor which should cover most of your needs, if like me you like rocks head to the second floor there is a great little store up there - I bought a few Amber specimens with spiders, ants and crickets in them for a reasonably cheap price.
