what a wonderful mum you are! It is fantastic that you want to be able to support her Journey. I have a friend who works at Western plains zoo...as a zoo keeper. Volunteering will make a big difference, I don't know how old you have to be to start though. The WIRES course is a great idea too. Volunteering at the zoo, if you can, or the RSPCA/animal shelters can help. I found this link - maybe you saw it already - So, you want to be a Zoo Keeper! | Taronga Conservation Society Australia. My friend did a bachelor of science (biology), but has probably done specific certificate courses too. She volunteered for a long time at taronga zoo and worked for RSPCA before landing her job.

When I was 10 I knew what I wanted to be when I grew up, it is very wise to acknowledge her and take her seriously. well done mumma!
