G'day! Most of my answers will relate to my own city - Sydney
How well are Christians and Christianity received?
In Sydney there's a large anti-religious pageant called the Sydney Gay and Lesbian Mardi Gras - where they often mock some religious leaders.
Depends then what sort of Christianity. In Sydney itself there is an area called 'the Bible-belt' which is generally the suburbs that are north-west of the city. An area generally called "The Hills". Moslems tend to live in the south, and south-west. Especially Lakemba, and the Canterbury-Bankstown area.
Jews concentrate in the eastern suburbs. There's a Baha'i temple in the north, but not well represented. Where I am, in the west we're truly 'multi-cultural', with Hindus, Moslems, Christians, etc.
Generally too the more expensive suburbs are in the north, and the east especially those closest to water - such as the harbour, and the beaches.
The poorest suburbs are in the south-west, whether they be closer to the city such as Lakemba, or further out near Campbeltown (such as Claymore).
There are some outer-westerns suburbs that are poor (just north of Mount Druitt there's a few like Shavely). And in the inner-city area there's an Aboriginal 'slum' near Redfern called "The Block".
One huge Christian group there is called
Hillsong which I think are now exporting their brand over-seas
How good in the middle class job market?
Employment is good. But it's like most places, IT, doctors, etc. you can get a job anywhere
Are most people content with the government or do they believe that it is not helping the citizens?
Depends. I support the Australian Labor Party (ALP) and they're in power both nationally and in my state. However state Labor are terrible as a government. Sydney has no long-term urban planning, never really has. Our roads sprawl out. Unlike Melbourne - if you see a map of central Melbourne, it's all perfectly aligned streets.
What is the perception crime and criminal activity, ie how close and severe do crimes seem to be?
Sydney has a relatively high crime-rate compared to other places in Australia but it's the largest city in Australia (also the oldest and the only 'world-city' in Australia)
Is there any kind of entitlement attitude especially from younger people?
I've no idea what this is
Ok this one is mine, how often do scary wild animals (crocs/snakes) come to populated areas?
Crocs are in the tropical north. Snakes are Australia-wide. Australia has 9 of the top 10 deadliest snakes. However in urban and built up areas you're not likely to see them. I've lived in Sydney most of my 42 years, and I've never seen one in Sydney.
Sydney does have a deadly spider, the Sydney Funnel Web spider. There's also a lesser deadly spider the Red-back Spider (I think it's related to the Black Widow).
We also has a coastal deadly creature the Blue-ringed octopus, which lives in some rock pools. There's no cure for its poison. However most people don't annoy it and so there's no incidents. Though if you do get bitten you better hope that there's someone who can give you CPR until the poison works its way out of you.
There are sharks in the seas and harbour, but shark nets keep most at bay.
There's no major diseases in Australia like rabies, or malaria. Because we're an island continent we've been able to keep out a lot of other diseases such as foot-and-mouth disease, mad cow disease, and anthrax. Quarantine and Customs get super annoyed if you come here with food items because some of these may contain pests or diseases.
The tropical areas, as well as having sharks, crocodiles, and several diseases I've just mentioned (such as Ross River Fever) also have cone fish and stone fish, which are nasty. There's also a jellyfish called the Box Jellyfish which have horrible stingers on them.
There are some local diseases such as Ross River Fever, but they're in the tropical north. I think they might have Dengue Fever too
These are probably first of series of questions, any and all advice would be welcome.
You're more than welcome
