Which subhurb in NSW for a young family?

Hi we are moving to NSW at the end of August 2019. We are very excited but we are struggling to decide on a subhurb. We will be renting at first to see how things go. My husband and I are both early 30s and our daughter has just turned 3 so we are looking for places which are safe, have good school and things going on. Ideally we would like a beach close by too (I know we want it all) I am a teacher and my husband is a plasterer/ renderer. Any suggestions would be great.
