Wake up! wake up! wake up!

Heres the deal ok. So ive just finished my first day in sydney and started the morning on my second one. Im staying at this hostel called wake up sydney, which is really nice and very very crowded, which is also quite nice. The one funny thing however is the fact that it feels like there are about 75% norweigans currently occupying the place and in doing so sparking some interesting conversations as one has to concentrate like never before just in order to understand them! But i quite enjoy challenges so its all good ; ) Now the other really quite funny thing is that everymorning and a couple of times during the day, the place is filled up by an aussie voice making announcements from the speakers around the hostel, yelling " wake up wake up wake up.... followed by whatever announcements he has, which is usally activities and happy hour specials down at the side bar. Not that i mind it, but it really makes you feel like you've landed in a high school movie, like grease, where at a certain time everyday a person decides to yell out announcements over the speaker!
Now if you're wondering what ive done, and will be doing, it is not that hard to tell! Sydney isnt the most commanding city and its not to hard to do what people say you have to do. For one you obviously have to see the opera house, which ive done, along with walked most of the inner city! After that its basically just going to the different beaches around sydney, like manly and Bondi beach etc. So as you can see i have quite a dilemma when it comes to activities that i have to do! I mean granted i go to all the beaches, then i can run through quite a lot of time. But after that what will i find myself doing, as ive already walked most of the streets one is to have walked. Now i do have lonely planet and i have decided to pick out a couple of museums that i want to go to, so ive got that sorted. But what is something amazing that i have to do and dont know about, besides skydiving(which im now thinking of most of the time)? If you happen to have any suggestions, please let me know! So there you have it... i really need to wake up wakeup wake up and find a lot of things to do as i have till monday before i start the surf tour to byron bay!
Cheers
