Hello! We are arriving in Sydney on Jan.30th and will spend 2 days there before starting our car journey up the coast to Pt.Stephens (and beyond). We'd like to put off renting our car until we're ready to leave Sydney- Is it possible to take a train to the Newcastle area and then rent a car there? Any suggestions as to how we would do that? If it's too difficult then we can simply go back to the Sydney airport and rent our car there, just trying to avoid going back that way, also might help us avoid some congested driving areas. We are looking at staying in either Bondi Beach or near the Circular Quay.
Thank you for any advice!
