Sounds like what you need is someone who knows what they are doing to show you what to do safely if you are asking questions like that.
Go to the uni climbing gym or the new gym when its open and start talking to people.
You can very safely top rope at Iris Moore from glued in bolts, but you need to know how to set an equalised anchor, belay safely and use appropriate ropes. Climbing forums arent really the place to learn practical stuff, though reading a getting started book and then putting things into practice helps . There are lots of easy climbing options at Port Stephens/ Watagans and central coast. Iris Moore only has a couple of routes under grade 20 though
