It’s not difficult to find fake medical certificates on the internet. It is not difficult to make yourself a fake medical certificate. However the SRC recommends that you do not use them EVER. In creating, buying and/or submitting a false medical certificate you are committing FRAUD. This isn’t just against University rules, it’s also against the law, and potentially carries the risk of a maximum prison sentence of ten years, if prosecuted by the police. It is unlikely that the police would prosecute you, but bear in mind that it is possible. The University also treats this as Academic Misconduct and carries a very likely outcome of a suspension from your studies for at least one semester.
The University is acutely aware that there are false medical certificates out there and routinely checks Special Consideration applications and the attached medical certificates. The chances of them finding any fake certificates is actually very high.
Some students have tried to get genuine medical certificates and have been tricked into paying for false ones. This is unlikely to be a good defense for you with the University. Instead of using online services, see your regular doctor, or if they are not available try the University’s Health Service (Level 3, Wentworth Building), or go to your local medical centre. If you are too sick to leave your home get an after hours doctor to come to your house. Google will give you a list of these services available in your area.
If you are stressed or struggling to the point that you even consider obtaining a false medical certificate, your best option is to talk to someone about what’s going on. The University has a free Counselling Service, or talk to your doctor, or ask an SRC Caseworker for a recommendation. There might be a way to manage your study load without risking far more serious consequences in the long term.
