Vish_mulay has articulated the situation quite nicely.
I have lived and worked in London, EU, NZ, stints in JP and HK and off course India. All in all, factoring in Life style, climate, work culture, wages, consistently low inflation opportunities and governance I have found Oz to be the best. That's not to say it's perfect but yes I have found it to be the best. Most people here who call them white pakis are arm chair Oz speciallists, haven't been there and have little,to no idea of the place. That's fine with me
Taxation remains high but delivery of civic sevices is very good. GST at 10 percent has remained unchanged for yonks.
Education standards and access to schools is very good. If you live in a schools catchment, you child is guaranteed a place in the school. There are selective schools if your prefer and private schools for the well heeled. Quality of public schools is just fine. Thank you.
Medical facilities are top,notch and even in government facilities. Often, if you have insurance and prefer to be a private patient, you share the same facilities as public patients in the same hospital except you get to choose your doctor

ergo in the same hospital you can be a public patient with no choice of Doctor or a private patient who gets to nominate a Doctor.
Then, there are private only hospitals.
While I undersstand and appreciate that others have different values and priorities that they consider important, I have my own, in which quality of governance and transparency come before religious structures of any denomination and goats, cows, buffaloes, rats or any other animal .

. Yes, i should be flogged and lynched
+108 to Vosh for highlighting the visa rorts by a certain section. While, unpleasant to discuss it is a fact.
The 457 was being mis used even by medium to large desi companies. I am at the Sr management technology client side coal face and speaking not from one but too many instances over many years. Eg. A local DBA worth $120k was undercut by onsite
DOO being paid $60k - that's half. If we don't provide accomodation then these DOO's live in hovels with 6-8 people in. 2 bed to an apartment.
The student visa thing is a even bigger racket.
While it's ok and justifiable to celebrate Dharmics swarming all parts of the globe incl. Oz The 457 visa became a racket and its natural it should be tightened.
As for me, I did not go on a 457 or student visa (my dad was not well off/ or corrupt) went the long hard way on a PR and was jobless, homeless and with a princely sum of AUD 2060 in my pocket the moment I set foot in Sir Kingsford Smith airport. The journey began from there.
