Temporary 457 Visa Holders
The New South Wales and Australian Capital Territories education authorities have stated that temporary 457 visa holders, and other temporary residents, are not eligible for subsidised education in Government schools.
Consequently, fees in NSW can vary between $4,000 and $6,000.
In the ACT, it is even higher at between $9,000 and $14,000.
Details of Visa numbers and related conditions applying to enrolment in a NSW Government school can be found at: www.schools.nsw.edu.au
The other States: Queensland, South Australia, Tasmania, Victoria, Western Australia and The Northern Territory do allow temporary 457 visa holders the same subsidised education that Citizens and Permanent Residents receive.
NSW 2010 Annual Fees were:
Primary school Years K-6 $4,500
Junior high school Years 7–10 $4,500
Senior high school Years 11–12 $5,500

I totally disagree with the NSW and ACT on this policy. Some 457 visa holders have almost 100% education subsidy paid in their countries to come and work in Australia where we pay taxes to Australia and at the same time contribute to develop the economy of Australia. It is totally unfair for us. Hwy other states allow subsidy whilst not these stated.
Thanks for allowing me to air my comment.
I agree with you. Australia is too lenient.
Another one, that I think you would disagree with, is the Travel concessions for students.
An overseas foreign student is able to claim a concession card to allow them cheap travel, because their income is low. Ignore the fact that someone is able to pay substantial amounts for them to come here and pay for private study, in this country of their choice, and in their financial capability.
There are more of these examples in other areas.
I have been in the ACT since Nov 2010 on a 457 visa and my children do not need to pay international school fees!!! We are here on a 457 visa but to be honest you need to check that your skills code(DIAC – code I think) is on the shortage list, if that is the case then you do not pay fees.

Is it the school that determined this, or the correct Education Finance department. Some schools have stuffed up ih the past and just allowed it without checking. One local school allowed a child on a parents student visa to have free schooling
But only for the first year…. it changed once they realised the error.
