Swimming with sharks

I'm trying not to take Laura's choice of birthday present as a hint - a morning of swimming with sharks in Manly Aquarium, followed by a session taking part in their feeding frenzy. I was certainly hoping they hadn't developed a taste for English people! Thanks to the cold sea temperatures still being chilly, the sharks were pretty dozy, but the stingrays were fairly frenzied! Luckily I managed to suvive with all body parts intact!
