You must be 18 to 30 years of age when you apply for this visa. However, if you are from Canada, the Republic of Ireland or France you are allowed to be up to 35 years of age at the time of your application. If you are the 30 when you apply but turn 31 before you are granted the visa you can still be granted the visa, and the same applies to citizens of Canada, the Republic of Ireland or France, who can be 35 but turn 36 before a decision is made.
