Sydney to Thailand Travel Guide

Thailand is one of the most popular countries in the Southeast Asia, opening its doors to over 32 million travellers a year. It famously serves up a well-trod backpacker route of gleaming temples, sandy beaches, spectacular islands, frenetic cities – and legendary full moon parties.
But it’s also increasingly the stomping ground of luxury beach hotels and adventure tours that veer right off the beaten track.
Travelling from Sydney? It’s usually cheaper and easier to catch a direct flight to one of the big cities like Bangkok or Phuket. Flights start at just over 9 hours long.

Book a flight from Sydney to Thailand, and you’ll discover a country that dishes up some of the most spectacular scenery on the planet.
The capital, Bangkok, is a firecracker. The Grand Palace, Wat Phra Kaew and Wat Arun showcase its grand past history, while lively Khao San Road is a neon-lit backpacker haunt. Patong in Phuket also pulls out the big guns, serving up 24/7 bars and clubs by the beach.
For something a little different, head for the Phi Phi Islands, where white-gold beaches pair up with sky-scraping rock formations. Or make tracks for central Thailand. Here, Kaho Yai National Park shelters waterfalls and elephants.
