We will be in Sydney Jan 13-23. This will be our 3rd trip there. In the past we've also visited Melbourne, GBR, Adelaide, Kangaroo Island, Blue Mountains. We will be spending our entire trip this time in Sydney since our daughter will be at UNSW. I've booked us on the 'Last Riverboat Postman' on Hawkesbury River, but we would also like to take a small (no big buses please) tour to Kiama, Jervis Bay and to see the Dolphins. BUT, I emailed a couple tour operators - one responded but with no definite cost,etc. and the other I have yet to hear from. Does anyone know of a tour operator that does SMALL groups, etc.? And, that will respond?
