The penguins, which the island is famed for, tend to hide or go out fishing during the day so we didn't see any whilst wondering about. Luckily for a small fee ($23 for ferry and admission) you can meet the penguins at the Discovery Centre and watch them be fed at one of three daily shows.
You can also opt to do a glass bottomed boat tour, dolphin swim or kayak tour, which allows you to extra the marine park further. But for today penguins, snorkelling and sunbathing was quite enough. Penguin island is a brilliant day out if you're in the Rockingham area, and perfectly affordable. Make sure you take a packed lunch and plenty of water though as there's no shops on the island!
