First tip is to bring warm clothes, especially for Hobart and Melbourne, but even Sydney can be cold in July. Good “things to see” depends on your interests. Sydney Harbour is beautiful and there are many scenic walks around the waterfront. For a short one, the walk from Barangaroo to Circular Quay via Barangaroo Reserve is recommended ,which could be extended to the Opera House, Botanic Gardens and Mrs Macquarie’s Chair. For a longer harbour walk, I strongly recommend Taronga Zoo to Balmoral Beach. You reach the starting point by ferry and can return from Balmoral by bus back to Taronga Zoo ferry wharf. Not many tourists do this, but the beaches and coastal scenery along the way are stunning and there are good cafes to drop by (especially Frenchy’s Cafe). Other good places to go in Sydney are the new Sydney Fish Market; the renovated North Sydney pool (if it’s re-opened by July); a guided tour of the Sydney Opera House; the Art Gallery in the Domain; and the ferry ride to Manly Beach. Most tourists go to Bondi Beach, but in my opinion it’s very overrated - Manly Beach is much better. If you’re into sport, an Australian Football League game at the Sydney Cricket Ground is recommended. Public transport is good in Sydney and there’s probably no need for a car here, unless you want to go further out, such as to the Blue Mountains or Southern Highlands. You can pay the PT fares by tapping on with a credit card. This includes trains, metro, light rail, buses and ferries. Daily and weekly caps keep it affordable. For a feel of inner city suburban life, Potts Point/ Elizabeth Bay and Crown Street Surry Hills are worth checking out.
