The process is not as bad as it sounds,  for private sellers all you need is your drivers licence number,  Bank Account Name, BSB and  ACC numbers.  Then you have to upload   a Bank Statement (less than 3 months old)  Note, I just downloaded and provided a proof of balance and that was sufficient.

I am pretty sure the name of the ebay account holder  and that of the bank account have to match

For business accounts you had to include  ABN, ACN  and details of anyone with more than 25% share
