After I've researched, I've found that actually Australian government has considered the fight againsty homelessness with a good budget.
https://www.dss.gov.au/sites/default/files/documents/10_2018/dss_annual_report.pdfWith a bit search, I found the budget of this department is not so bad.
The department supported the commencement of the National Housing and Homelessness Agreement on 1 July 2018. It provides ongoing funding to states and
territories totalling $1.5 billion each year to improve housing outcomes and reduce the incidence of homelessness.
As we see that the department supported reduce the incidence of homelessness with $1.5 billion each year. This is actually a good number.
I have estimated a cost of build a house it find its residents a job and rehability them cost with $200.000.
Then 1.500.000.000/200.000= 7.500 This is number of house you can build in a year and find a job of its owners.
There is 110.000 total homelesses. So, 110.000 homelesses / 7.500 decrease number per year= 15 years the solving the problem. It maybe better but not so bad for now.
But the problem is; corruption!
Lets examine the bugdet details:
As we clearly see that, although total budget is $1.5 billion, but only 1,6 million of them were separated from the budget to homelesnesses. It is about 1 in 1.000 of all budget.
So what will happened the remained $1.499 billion? Affordable Housing, Support for Outcome, Totals by appropriation type, Disability Mental Health and Carer, National Disability Insurance, so and so, so and so. All these are just word salad for just hiding the corruption.
With $1,6 million you can build only number of home: 5 or 10. With this speed, you can finish the homelessness in 11.000 year, estimated the year of 13.019.
Inother say, homelessness in Australia will be end in year of 13.019 estimated because of Corruption in Australian government. If we consider the population growth rate is more than that, we can clearly say that homelessness in Australia will be continue forever till infinity.
