September 30 deadline is for loans to US lenders. I would presume CBA is not classed as a US lender. An exert:

'The mall operator in May won a reprieve until Sept. 30 on $1.1 billion owed to U.S. lenders. Centro at the same time won an extension until Dec. 15 on A$2.3 billion owed to Australian creditors and $450 million owed to U.S. noteholders. The second extension relies on Centro satisfying U.S. lenders by the end of this month.'

Obviously if US defaults then Australian lenders also become an issue. So when you say 'dont think we will have to wait till December', this implies that you don't think the extension September 30 will be granted.
