Hi Infose,My understanding was that any payments to trustees are not on.
Remunerate can be interpreted in a number of ways.
But the ato is pretty clear about payment.

This link is to the ATO's booklet on SMSF's, page 5 of interest to you.
I vaguely remember problems such as yours forced me to separate the corporate trustees, but a long time ago, cant remember the details.
