Each award is also complex, and covers a range of issues in the employment. For example, this is the Professional Employee award:
https://awards.fairwork.gov.au/MA000065.html just working out what the minimum wage would be for a graduate engineer with 2 years experience is a complex, detailed matter.
But yes, probably, for most professions you could reasonably expect to support a family of 5 on the award, depending on location and definition of "support". Affording a house would largely depend on an additional inheritance, though.
Is "inheritance" used in a different way here similar to how "award" is, or are you saying you often need to inherit money from your family in order to be able to buy a house in Australia?
No, it's used in the same way as elsewhere in the Anglosphere. And yes, as in the rest of the Anglosphere, generally you need an inheritance to be able to afford to buy property.
"in the high cost of living areas" is the rest of that sentence.
It is perfectly doable, even common, to buy a home in low and medium COL areas without any assistance from family, living or dead. The fact that you can't do this in NYC or SF is not an indictment of anything other than NYC and SF.

Tell me a place in any Western society (outside of run-down rural areas/flyover states) where an average employee (i.e. no ultra-rich tech hipster bros) is able to afford a home before the age of 30 purely by his own savings and income. That is frankly no longer a reality for most people.
