Aus visa expired continued to use bank checking acount

I was in Australia for 1 yr during 2009-2010 on a student visa.
During that period I started a private limited company[software development services] for future activities.

There was no activity with my company during my stay in Aus

My visa was cancelled in Jan 2010 but I continued to use my checking account to receive payments till now as if I am operating in Australia.

Now I do not have cheque book or atm card to draw that money now.
What can I do now? Bank says to visit bank personally to resolve the issue.
