NSW Do Minors have Equivalent Rights to Adults in NSW?

[Tim W]

Well I highly enjoy law, when a business or person for example breaches a law and I inform them of it, they tend to refer to my age e.g. 'what would you know'. This is where my question comes in because I haven't been able to found any legislation which contradicts my rights due to being a minor. An example is from yesterday, I door-to-door salesman claimed he would not leave my premises until I purchased a product, I then reminded him of the law and how he was breaching it. He then said I was making it up, I then had to threaten to call the police which caused him to flee.

While on the one hand, I encourage the ordinary citizen to understand their rights and duties,
on the other, I would discourage dilettante non-lawyers from engaging in legal debate with third parties,
(as in "...and I inform them of it...")
for the same reasons I would discourage First Aiders from performing neurosurgery...
