Really the universities should be providing more opportunities and support for these students to learn English, most of them have good technical English but its the conversational English that they really need help with.

Also the various levels of Australian government need to take seriously the need to plan and improve infrastructure if they want the economic (and tax revenue) benefits they are currently reaping from the migration boom to continue, so that this country can continue to be a desirable place to migrate too.

Australia is significantly short in a wide range of professions and trades….for example, where are all the nurses and doctors going to come from to deal with the changing demographics of the Australian population? Just too look at one sector of the employment market……

You left out a few things. You forgot to insinuate them with being responsible for:

high world oil price;
El Nino;
the War on Terror;
not having polygamy available as a lifestyle choice;
not being able to park closer to the train station;
the AFL Grand Final being held at night;
the children overboard;
restaurants serving other than meat and 3 veg;
falling numbers down at the bowling club;
most things you want to complain about……

Both Japan and Italy already have far older populations than us, and as far as I know they still have good quality health-care. Mass immigration can only defer the inevitable aging of the population it can’t stop it. How many overseas students are in nursing or medical courses, I know of large numbers in business and accounting type courses. Some of these students go so far as to admit after failing exams and appearing before exclusion committees that they are only doing the course to get permanent residency.
Cries of labour shortages are very tiresome coming from employer groups and those on the right of politics. Give us evidence and objective analysis.

Looking at things another way, John, how many more people can live in your house? your neighbors? your suburb? your state? and Australia as a whole?
Whatever it is, it is finite. Look at were we live on our continent, mainly in the coastal regions of Eastern and South-Eastern Australia, with another pocket in the South West. There is a reason for this and a reason why Alice Springs is not a mega-city. Australia is a dry continent with mostly poor soils. If you take into account peak-oil and climate change we will have trouble supporting our current population let alone catering for the 350,000+ per annum new arrivals.
At some point growth has to stop, why not slow things down now instead of being forced to in the future when it will be far more difficult to manage things?

John Roberts who is paying me for all the problems caused by increasing our population?

Some people and sectors of our economy are booming from the record high overseas immigration, it is just that only a minority benefit (real estate, media, financial services and associated areas) at the expense of everyone else.
