Visa's are very easy to obtain with a lot of working holiday visa's now being processed in as little as 48hours. You can get more information on applying for all types of Visas under the 'Visa Information' section on this website.
Nowadays, there are so many easy options for Australia i.e you could go as a tourist, go on a 1yr working visa, apply for your 2nd year visa, look into sponsorship visas and skilled visas. A lot of people generally go to the land down under and find themselves drawn to the lifestyle with no plans to every leave. If this is what you are looking for then Oz is certainly an easy place to go. On the other hand, I would encourage anybody to carry on travelling after being to Oz and explore other parts of the world before settling down, if this is what you had planned to begin with. You don't want to regret not seeing other parts of the world in ten years time, and who knows, you might find somewhere you thought you would never love as much as Oz.
Flights down under, compared to when I went in 2007, are very well priced and some companies have really great deals. You could even opt for a round the world trip which will help you take in more countries on your trip and fill up that passport with exotic stamps. This is a great way to save money and see as much as possible. They are pretty flexible and there are a lot of great companies linked on this website to check out.
Another highlight of Oz, is the high wages. Work is vast in Australia and the wages are really outstanding, compared to European standards. You can get a well paid job doing anything from waitressing to farm work to office jobs. The options are endless. There are so many sights to see in Australia and there is no doubt that you will need a whole year to see them all. A year sounds like a long time, but believe me it really isn't. It will fly by so fast that all you will think of is the well known saying 'time flies when you're having fun', because in Oz, it really does.
There are so many places in Australia to start in, with the most popular being Sydney, Perth and Melbourne. Common trips include The Great Ocean Road, The east coast (Sydney-Cairns) and the journey through the centre of the country- probably my favourite. Australia has so much to offer that it seems almost rude not to see as much of it as there is during your year there, especially with hostels and travel being pretty inexpensive! If you opt for two years then you will certainly do that. Travelling is about doing exactly that, work to travel don't travel to work, unless that is you're initial aim, then by all means get a job and work away, but if you are backpacking then try and take in as much of the country, culture and people as you can because this is what you will remember in 20 years... Believe me! If you are interested in this option don't hesitate to contact me for info on itineraries, ideas and options, I have travelled the whole country so I can help you as much as you need!
