Picking up odd jobs while backpacking can be a great way to sustain your travels. Common opportunities include working in hostels, bars, farms (WWOOFing is popular), or teaching English if you're in the right place. Australia and New Zealand often have working holiday visas that make finding temporary jobs easier, though they do require a visa. Southeast Asia and certain parts of Europe can have opportunities, especially in tourism-heavy areas. Websites like Workaway, HelpX, or local Facebook groups can help you find gigs. Always check visa regulations for each country to stay within the law. Safe travels!
