Even a one year old can enjoy Questacon. This review is mainly focused at that age group.
My daughter (Miss 1) is 13 months and we have been taking her to Questacon since she was 10.5 months.
The MiniQ section is great with a different number of areas - ones that Miss 1 is interested in is the baby play area, a water play area (her favourite section), sensory area and a section about space. She also likes to have a look around the other bits and pieces.
The staff that look after the MiniQ section have always been very friendly and helpful.
Miss 1 also loves to look at the bigger exhibits, but I usually find it too crowded to get her in to have a look at them properly and she's a bit too young for most of them. She enjoys the entrance though with the mechanical robot and funny mirrors.
Only downside to Questacon (in my opinion) is the price - $23 for an adult, $17.50 for a child between 4-16 and under 4s are free. We have gone a number of times and have found the family pass the best way to go.
What a fantastic interactive world of science. An enjoyable day out for both adults of all ages as well as children. My four year old had a fantasic time playing with her poppy at Questacron. We will definatly go again on our next visit to Canberra.
