The bank will generally take security over your business assets by way of a General Security Agreement registered on the PPSR.  This is the new version of the old form of debenture which is a floating charge over the company’s or business’ assets.  This allows you to continue trading without recourse to the bank for consent to deal with any transactions that are in the ordinary course of trade.  Generally anything not in the ordinary course of trade would require the bank’s consent (e.g. sale of part of your business etc).  The bank will also take security against any real property; your house and any other property investments.  In exchange for secured lending, your interest rates ought to be lower depending on your risk profile.
