If you're thinking of travelling to Oz, you are going to want to know some of the important information. Wi-Fi's going to be an essential if you want to tweet a picture of the Sydney Opera House, or make a few status updates on Facebook to make your friends jealous! 

Global Roaming

When travelling anywhere, it's important to organise how you're going to connect your phone to international data providers. In other words, giving you access to 3G abroad. It's unlikely that you'll need data in the big cities with all the Wi-Fi hotspots available, but if it's necessary, here's what you'll need to do: 

Invest in an International Data Roaming Pack from your provider for your smartphone. This will give you data to use while you're in Australia, provided that your network carrier supports Australian connections. Providers that allow this include Virgin and Vodaphone. Make sure you check this before travelling.  

A more cost-effective method is swapping your SIM for a prepaid, local card that you can purchase when you arrive. Your hotel concierge will be able to provide you with a recommendation, or you can find them at mobile phone stores, newsagents or supermarkets. This will allow you to connect to 3G at affordable rates. 

Sydney

Sydney is Australia's most populous city and one of the most multicultural cities in the world. It's home to two major landmarks in Australia - Sydney Opera House and Sydney Harbour Bridge. 

Finding Wi-Fi in Sydney is not difficult whatsoever. The city is abundant with cafes, bars, restaurants and libraries that all provide free internet connection, as well as train stations, Sydney airport and several ferry routes, so you'll able to stay connected while you travel around the city.
