Why don't alcohol laws contradict the constitution (or other laws in some cases, like in the example below, because The Age Discrimination Act is not part of the constitution)?
I think it is age discrimination. If not, why wouldn't it be?
For example, in Australia, the The Age Discrimination Act (2004) prohibits age discrimination in the following areas (emphasis mine):
Discrimination in employment, education, access to premises, provision of goods, services and facilities, accommodation, disposal of land, administration of Commonwealth laws and programs, and requests for information.
I checked that it is not one of the exemptions listed below the second bold header.
I wonder about this specific case as well as the general case.
