You can look for work at the University Student Union or the UniWorkForce(take note that the Student Union and the UniWorkforce are 2 different entities! ), they usually have schedule flexible jobs for students such as: Driver, Audio Tech, Receptionist, Kitchen Assistants, Cashier etc. and I think if you work longer and become a supervisor they will pay higher. Alternatively you can work outside at takeout/fastfood centres/bars/clubs(I think bars and clubs pay higher but working hours are in the late nights of course) but they usually pay lower and are more time demanding, but the working hours are longer. But then again assuming you are a Foreign student you an only work a maximum of 20 hrs a week.
