This is the plan: arrive in Sydney, drive slowly south along the South Pacific coast to Melbourne, taking a week to do it. We'll stop along the way. Then drive (on a freeway) back to Sydney and then to Hunter Valley (wine growing region). Then back to Sydney for a flight to Cairns. We'll stay there 5 days, snorkeling on the Great Barrier Reef and visiting a rain forest. Then back to Sydney for our flight home. Three weeks total.
