Was looking for some tickets of SeaLife Melbourne and found this code online to get one ticket of similar or less price with the purchase of one. I think it is not advertised officially, and not sure how long it will last.
It was a very popular deal before and I could not find any current deal of this in OzBargain. Hope it helps someone :)
Took my mum and my kids the other day for a belated birthday, it's still pretty good for a few hours. My kids (5,2) enjoyed it but there is only so much looking you can convince kids to do, not as good as the zoo where you can find some grass and let them look for 15 minutes to get their head back in the game.
