is ielts compulsory for Australia Skilled Visa?i'm Applying for Australia (Melbourne) Skilled Visa ....<br />

Your question is not very clear. It depends on exactly what catagory visa you are applying for. However if you are a citizen from an English Speaking country like the USA, Canada, UK it may be waivered in some cases if you can Prove it.

hello,
i must say that your question is really knotty.
so, the Basic Requirements for an Australia Skilled Visa include:
* Age - you must be under 45 when you apply;
* English language - you should have sufficient ability in the English language to work in Australia (at least at a vocational level);
* Qualifications - you must have post-secondary qualifications and your skills must be assessed by the relevant assessing authority as suitable for your nominated occupation;
* Nominated occupation - when you apply you nominate a skilled occupation, which fits your skills and qualifications. Your nominated occupation must be found on the Skilled Occupations List;
* Recent work experience - the period of work experience required will vary depending on the number of points you may be granted for your nominated occupation;
* Australian qualification exemption - you do not need to meet the work experience requirement if you have completed an Australian qualification less than 6 months before lodging your visa application; and
* Skills assessment - before you apply, you must have your skills assessed by the Australian assessing authority designated to assess your nominated occupation.
* Health assessment - you should be of reasonably good health and all applicants must have their health assessed by a panel doctor and undergo a medical examination.
* Character assessment - you should be of good character and this too will be assessed.

if you meet all these requirements you can apply for visa.
