This is a satire on the Australian housing market, the unemployment crisis and the state of welfare (nonexistent).
The Betoota Advocate often frames its articles as local news, but they're referencing national events.
Since the 2019 election and the formation of the Australian Affordable Housing Party, there's been increased pressure for more affordable and more accessible housing in Australia, as well as fairer laws for renters.
The French Quarter is symbolic of Australian urban centres. Most people who work in low paying jobs here can't afford to live near where they work. People on welfare (and welfare payments here are under the Henderson poverty line) also can't afford to live near where jobs are. Additionally, the government's solution has famously been that these people need to move further away from the city, to where the more affordable housing is.
The final paragraph referring to building more houses on the edge of town isn't talking about a disagreement over where a specific development is being put, it's referencing that official government policy. You can actually get more money on welfare if you move away from the city.
However, the writer is lampshading it, by having the character immediately call attention to the fact that the people who he wants to move away from "The French Quarter" are the very people whose labour he wants to take advantage of.
The article isn't about elderly people, it's about wealthy boomers acting like vampires, that's why they're referred to as "the living dead" and not simply retirees.
