What are some tips for navigating public transport while visiting Sydney?

Using an Opal card is highly recommended for easy access to trains, buses, and ferries; it simplifies payments and offers discounts on fares. • Make sure to download the Transport for NSW app for real-time updates on schedules and service disruptions; it's a lifesaver when you're on the go. • Plan your route in advance and consider peak hours to avoid crowded buses and trains, especially during weekends or public holidays.
