Things about Australia that seem bizarre

This course costs $5200. It's called Captive Animals, Certificate III. This is the advanced certificate - ideally you'd have Certificate II before you spend an extra $5200 to get the Certificate III. Taking care of animals in cages. As someone who grew up in the country, it seems incredibly bizarre that you would not only have to get a certificate, you'd have to pay extra money to get the advanced certificate to do something like this. I could see getting some training - but $5200 worth? For a job like this? This is not even the level of a veterinary assistant - it's just cleaning cages; feeding animals?! Yeah, diseases, hygiene, blah, blah, blah - maybe a week of material? Nobody cleaning cages is going to remember all the potential pathenogenic agents - they'll just know a) get your shots and b) don't get bitten.
