It seems that maybe either way is acceptable cause my accountant says it should be the Trust's ABN, my solicitor says its the Trustees ACN, my friend (who has a family trust) says its the Trust's ABN. To me, it seems logical to include the Trust's ABN since afterall the Trust owns the asset. The Trustee doesn't own the asset, their sole purpose is to act as trustee.
Maybe, I'll just go with my solicitor's advise. Tony
