Don’t you need ‘the’ in front of ‘Australia’s response’? I think I'm now hearing ‘the’; and for the NP, Australia’s response, is followed by its modifier, it seems that a definite article needs to be in there. Isn’t there ‘the’ in the presenter's saying?
No you wouldn't say:
the Australia’s response
You would say:
the Australian response
It is OK as written, unless unique to Australian English (I am AmE).
I can't tell if the announcer said the, if so its barely there.
There is generally no article when a singular proper noun is used as a possessive:
- Beethoven's Fifth Symphany. John's car. Einstein's theory of relativity.
Plural proper nouns used as possessives generally do use an article:
- The Beethovens's dinner was getting cold. The Yankees' locker room. The Marx Brothers' last film.
We don't use articles with determiners that function as possessives (sometimes called possessive pronouns):
His most famous work. His car. His theory.
There are exceptions, fixed expressions, and special ways to create particular meanings--That's the Mary's smile I wanted to see.
