A little bit outside of Macarthur but only 40 minutes easy drive from Campbelltown, the Wollongong Science Centre and Planetarium is well worth a visit and makes for a great family day out.
There are lots of hands-on displays and free shows including the popular bubble and balloons show. The laser show is a small additional cost to the entry fee but should be experienced at least once.
The two-level centre is toddler friendly - although some get scared of the dinosaur displays - and suitable for ages 2 to 14 though adults can have fun too. Prams can be accommodated and there is a storage area for bags and strollers. There is also an on-site cafe and outdoor picnic area. Toilets are clean and well maintained. Lots of volunteer staff around to assist with explaining the different displays and answering the neverending "Why?"
Many of the interactive exhibits have been donated from Questacon. We visit at least once a year and there is always something new on display. The Science Centre is part of the University of Wollongong and open from 10-4 most days including public holidays. There is an adjoining shop which is well equipped and sells a range of fun stuff as well as local crafts.
