Practical Logistics

Getting Around

• Domestic flights: Qantas, Virgin Australia, and Jetstar connect all major stops. Book early for the best fares.
• Car rental: Handy for day trips like the Great Ocean Road, Barossa, Daintree, and Kangaroo Island. Drive on the left, obey rural speed limits, and watch for wildlife at dawn and dusk.
• Trains and buses: Good within cities. The Ghan and Indian Pacific are iconic long-distance trains, but they require more time than this itinerary allows.

Entry, Money, and Connectivity

• Visas: Most travelers need an eVisitor or ETA before arrival. Apply online and carry the same passport used for the application.
• Currency: Australian Dollar. Cards are widely accepted and contactless is standard. ATMs are plentiful.
• SIM and data: Buy a local SIM on arrival from Telstra, Optus, or Vodafone for strong coverage. Free Wi-Fi is common in city centers.
• Power: 230 V with Type I plug. Bring a universal adapter.

Health and Safety

• Sun protection: UV is strong year-round. Wear a hat, sunglasses, and high-SPF reef-safe sunscreen.
• Water: Tap water is safe to drink in cities and towns. Carry a refillable bottle.
• Wildlife: Do not feed wild animals. Keep a respectful distance from all wildlife including marine life.
• Swimming: Follow local signs, swim between the flags on patrolled beaches, and heed stinger season advice in the tropics.

Best Time to Travel

• April to October: Ideal for the Red Centre and the tropical north. Cooler desert days, less rain, lower humidity, and calmer reef conditions. Southern cities are cooler in winter months.
• November to March: Best for beaches in the south and the Great Ocean Road. Expect summer heat in the cities and very hot conditions in the Red Centre. The tropical north has wet season with higher rain and possible stingers.

Balanced sweet spots:

• April to June and September to October. These shoulder periods offer comfortable weather across most regions and fewer crowds.
