What you need to know before you book your airfare and tickets
How about booking yourself a cheap flight to Sydney? The weather is famous for being excellent all year round, and the low exchange rate means you'll be able to have a great time there on a budget after getting the cheapest flight to Sydney.
After getting off your cheap flight to Sydney at Kingsford Smith airport, take the train to the Central Station. There's plenty of accommodation in the vicinity, budget or otherwise. It's at least a 24-hour flight from London to Sydney, so the first thing you probably want to do is to rest after that cheap flight to Sydney.
Once you're up and ready for some sight-seeing, take a walk down George Street to Circular Quay. Here, you'll find two of the sights that Sydney is most famous for - the Harbour Bridge and the Opera House, both within spitting distance of each other. You can also go for a stroll in The Rocks, a part of 'old Sydney' that has mostly been gentrified and turned into swanky fashion boutiques. Stop by for a drink in one of the old pubs and count yourself lucky that you managed to get the cheapest flight to Sydney instead of coming over by boat like most people did, even as late as the 1950s.
So, get to it and book yourself a cheap flight to Sydney right now!
