Purchase $10 or more at Gloria Jeans in Westfield Miranda (likely to be a Sydney-wide promo… It's on the Facebook page for GJ Figtree too) and you get a voucher for 2 for 1 entry to Wildlife Sydney Zoo. Present voucher for one free entry when accompanied by a full paying adult. Not valid with other offer, groups, adv bookings and combos or online tickets. Voucher valid until 30 June.
I purchased a small mint ice choc and a pear and raspberry bread and it came to $10 exactly. If anyone can confirm other stores with this promo - there was a poster for it and I could see the vouchers at the counter. Need to ask for vouchers as they don't tend to hand them put unless you ask.
Full price adult walk up tix are $40 so you'd be looking at spending $40 for 2 pax.
They have it advertised and a bunch of the vouchers on the counter at Queanbeyan store.
I just took one.
