I am planning to visit zoo with my kid next month. So was shopping around to find best price. I came across the www.isango.com.
If you select the date on www.isango.com from 1st April, 2016 price comes down to $28 i.e. 10% discount on the normal price.
Normal price for adult ticket on zoo.org.au is $31.60.
Cheers
That is not true… They kick you out at 5pm !
