Excellent services. The staff were amazing. Although if there was something that I could suggest to improve the services I’d say that snacks and drinks should be offered in between meals. Other than that then it was a lovely flight.

FAQs about flying to Sydney

Sydney climate

Sydney has a temperate climate with more than 300 sunny days a year. Winters are more cool than cold. June to August are the coolest, and the daytime temperature can drop to 7 degrees (Celsius). Summers are humid with occasional downpours. Temperatures are usually in the upper 20s but can go over 37. Sea breezes cool the hot days, and evenings are balmy.Autumn and spring are delightful with clear, warm days and mild nights.

Getting around Sydney

Sydney is a city built around its harbour, and that’s where you will find some of the best sightseeing. The public passenger ferries are run by Sydney Ferries and you can board a monorail down to Darling Harbour. There are plenty of ways to get around the city. The By Sydney Explorer and By Bondi Explorer buses stop almost anywhere you’d want to go in the city and around the harbor and beaches. Take the light-rail tram line to Chinatown, Paddy’s Markets or Darling Harbour. You don’t need to drive, and the one-way streets and lack of parking will eat up your time. Taxis are all over and easy to hail on the street. Adventurous travellers who don’t fear heights can join the Sydney Harbor Bridge climb, which walks across catwalks and ladders across the arch of the iconic Sydney Harbor Bridge. 

What is good to know if travelling to Sydney?

  • Lots of tourist activities in Sydney are all about the views such as climbing the Sydney Harbour Bridge. There are panoramic views from Mrs Maquarie’s (wife of Governor Macquarie) Chair, in the Royal Botanic Gardens (free to enter). The Open Air Cinema is close to the Chair. The big screen has the Sydney City Skyline, Sydney Opera House and Sydney Harbour Bridge as a backdrop.
  • Taronga Zoo was opened in 1916 and sits on high land along the waterfront overlooking the Sydney Harbour Bridge, the Cove and the Opera House. The zoo is just 12 minutes by ferry from the central business district. The Sky Safari cable car runs between the zoo wharf and the top of the zoo.
  • The Rocks is Sydney’s oldest preserved colonial area. It is where the first settlers from England landed in 1788. Today, having undergone a makeover, it is a thriving area of galleries, museums, restaurants, cafes and shops. Staying with settlements, Fort Denison was an unhappy place of punishment and confinement … for the convicts. It’s part of Sydney Harbour National Park and is open for guided tours.
  • Take the Manly Ferry. Hop on at Circular Quay and cruise the seven nautical miles (takes about 30 minutes each way) to Manly, the suburb by the sea. There’s a lot to do there apart from going to the beach: several heritage walks, galleries and museums, regular festivals and more than 80 restaurants. 
  • For a view of the city and beyond, visit The Sydney Tower, 250 metres (820 feet) above the streets. High-speed double-decker lifts rocket up to the observation desk in just 40 seconds.
  • And beaches. Don’t forget the beaches: Bondi, Manly, Coogee, Balmoral, Tamarama and Palm.

    Peak season: The Sydney festival starts just after New Year’s and runs through January.

There is yacht racing on summer weekends, and the start of the Sydney to Hobart Yacht Race is on Boxing Day (26 December).
