Late night disturbance from swimming pool – Sydney

I managed to get a ground floor flat in Kingsford next to UNSW. Nice flat, new complex, safe area etc. perfect to start I though. The thing is that due to the proximity of the complex to the university, there are a lot of students living here.

I asked specifically to the agent before signing the contract about parties and noise levels and he told me that the complex is ruled by strict rules regarding the noise and disturbance and so on.. The thing is that my flat is next door (wall to wall) to a small indoor swimming pool with a lot of echo. the time table of the pool is up to 8:00pm but I use to be bothered by loud noises as consequently the pool is used for fun and parties with alcohol late night (from 8 to passed midnight)

What I have been doing is changing my pjs, putting my jeans, going to the pool and kicking them out (pictures includes) telling that they will be reported if I see them again after 8:00pm (with not success) just like an grumpy old guy. I also sent an email to the state management and the ask me to call the emergency line in every occurrence, however, the thing is so frequent that I don't think that I have to sleep with the phone next to me to call them every time when they should ensure that the rules or the pool are accomplished (or enforced).

I am not like that, I try to keep it cool and I use to hang out with younger people. I have tried to be patient but this thing is so frequent (and variate) that is taking out of my nerves, so my question is: apart of the emails and complaints to the agent (they administrate the complex), if there are another instance that I can recur (perhaps the city council? police?) or any other way to formally elevate my complaints to higher or different instances and on the other hand, if this is a reasonably reason to break my contract and move from here avoiding paying the penalty fee for early cancelation.

Any comment would be really appreciated. Thanks!
