Salaries will vary from school to school and country to country. It's important to remember that although some countries have a much higher average salary than others, the cost of living in that country is probably higher as well. Also, while some countries may appear to have a much lower teaching salary than you may be used to, the cost of living in these countries is usually considerably lower.
You also need to read the job description carefully. For example, not all schools will provide you with free accommodation, therefore you need to understand that a percentage of your monthly salary will go towards paying rent on housing.
