My kids are 11 and 13 and really enjoyed the visit. It's quite small compared to Questacon but we found the displays and information to be of a higher quality and much more detailed and we ended up spending longer here. The displays are very reliant on interactive touchscreen technology, there are lots of individual videos and 2 theatrettes, one of which plays a 3D film. The displays are about CSIROs areas of interest so predominantly about the environment, agriculture and health. Their target 'market' is late primary and upwards. It's not the place to take little kids but great for older ones if they have an interest in science. The little gift shop (mostly selling books) is really good with lots of choices in that hard-to-find level for kids who are well above picture books and 'junior' readers but not yet into adult books.
