Hello Travel! I have done some searching and havent found what Im looking for, hopefully someone can help me!

Next year in Feb/March I will be starting a year(ish) long adventure to Brazil and Canada. In Brazil I will be wwoofing and staying with family as well as doing touristy stuff. Since my Mum is from Brazil I should be able to get a passport to Brazil too. However I wanted to have an extended stay in Canada and thought a Working Holiday Visa would be the best bet (So I can also legally work there to earn more $ to travel more)

However, the working holiday visa program application date doesnt start until I leave Australia. Does anyone know if I can apply for this while NOT in Australia?
