Today Oz Ebay sent out an email

"Current policies regarding accepted payment methods still apply. This means PayPal is required on all listings on eBay.com.au. Other payment methods (i.e. bank deposit, cheque/money order) may also be offered until 15 July 2008.

As previously communicated any listings that do not comply with eBay's Accepted Payments Policy will be removed. We strongly recommend that in order to ensure your listings comply with the Accepted Payments Policy you remove any details of payment methods other than PayPal or pay on pick up within the item description. Listings that have other payment methods offered within the payment options field will be allowed to expire as these options will not be displayed to buyers from 15 July 2008.

The decision to delay these changes was made by eBay following the Australian Competition and Consumer Commission's (ACCC) draft notice issued on Thursday 12 June 2008.

eBay released a media statement on Friday 13 June regarding the ACCC's draft notice.

Please note that some of our onsite communications will still refer to changes taking place on 17 June 2008. These communications are being updated and should reflect the new date of 15 July 2008 within the coming days. "

Looks like they are determined to have a run in with the ACCC...
