Nope, not unusual at all (though their may be some that do), I have never been asked for proof of income for the several ML's I have had over 2 decades. ML's are based around the security of the shares ie if you don't pay the interest bill OR the value of the shares falls below the LVR (+ a small margin) then they simply sell the shares from under you if you don't supply more cash or more security to get back under the LVR. ie anyone with an margin loan should be keeping a watchful eye on their loan facility.
Margin loans are a wonderful tool if used correctly, I have been using them off an on since the early '90's and run LVR's around 30% - 40% at most.
With all due respect, how don't you know this ? These are the sorts of questions you should have been asking before you took the loan out. I know you trusted your adviser but if you didn't understand would you not have asked them how an ML worked ?
Thanks for that..
No, I understand how they work, just did not 100% know if on establishment they require proof of income etc.
