If you realized that you cannot travel your entire trip without working then there are a couple of different options that you might want to look into. Finding work during your trip is easier than it seems. Here are some options that you might consider that don't require a visa:
- Teach English. English is the international language of business and of travelers. Almost every big city in the world will have schools that teach English to locals or to other travelers. You do not have to be a professional teacher to teach English. You only have to be a native English speaker. Most language schools require that you have a Tefla certificate. Once you are Tefla certified then you will be able to teach English anywhere around the world. Some language schools that teach other languages then English still employ travelers to do office work. I would suggest stopping by any language school to see if they have work available.
- Hostels. Most hostels around the world employ travelers. You will notice this as soon as you check in at the front desk. You might not earn cash working in a hostel, but most of the time the owner of the hostel will give you a free place to stay and a meals for free. Work might consist of helping check in guests, changing bed sheets, or cleaning.
- Bar. There will always be a need for bar tenders or waiting staff in every city around the world. There are a lot of bars in popular tourist spots that have been opened by older travelers that never wanted to leave. Most bar owners will allow travelers to work in these bars for weeks at a time. Don't expect to earn tips like in the States, because tipping is not the same outside of the States. You will be paid an hourly income. This is a great way to meet people!
- Seasonal work. In Barcelona, Spain you can pass out fliers during the day and night for bars that are located on Las Ramblas. Most of these fliers promote a pub crawl or give out free drinks. I have met travelers that have made $900-1100 Euros each month during the summer by doing this 4 to 5 days a week. This is enough to pay for rent, food, and save money to go and travel. This job is only available during the summer though, because of how busy the city is from the tourist season. There are probably other jobs around the world like these depending on the season and the city.
- Sell things. Some travelers pay for their trip by making bracelets, earrings, or things along this line that they sell in markets, in the streets, or to other travelers. I have seen string bracelets made and sold in Buenos Aires, Argentina for 10 pesos. I have seen the same bracelets sold in Europe for 10 Euros. If you can sell your things in Australia or Europe you can make some pretty good money.
