I went here with my wife and young kids (7 & 5). There were some interesting things to look at, and if you are into learning about Aboriginal culture you will probably really enjoy it. My 5 yo son loves the dinosaurs and bone displays especially, though my 7 yo was totally freaked out by the ‘7 sisters’ art display. The kids loves the minerals and rocks display too.
They really need to fix up a few basic things though. The cafe outside the museum was poor - fridges full of hipster mineral drinks and all the rest, and a long line of people waiting with one person serving. Couldn’t even get a bottle of water on our trip there. They really need to do better here.
Also, we purchased our session tickets online, but when we went to access them it wouldn’t work (plus you have to create an account just to buy them) so I missed out on my welcome booklet that I purchased as I couldn’t show proof of purchase (even though the lady at the front outside said they had been having issues with people signing in to get their tickets). Pretty disappointing.
I would encourage everyone to go while it is free, not sure I would pay to go again, though the space itself and the exhibits are nice.
