Hi MMLI,
Generally speaking, anyone under 50 is eligible to apply provided they meet all the requirements. However, if your friend is between 45 and 50 then they may need to satisfy higher requirements, for example, having superior English language skills as oppose to a competent or proficient level.
I would be more than happy to do a free assessment on your friend if they send an email to
info@affinitymigration.com.au or I can arrange a time to meet with them in person and discuss their options. I will be in HK until 5th January.
I look forward to your response.
