Hi Gareth, you can buy it online at ideli.com.au, david jones food hall, leos at kew and Thomas Dux stores.
Yea brand clotted cream is made to a different process to what you would be used to in the Mother country. The most noticeable difference is it does not have the crust. I'm sure you will be happy with the rich caramel taste and the thick consistency of the product though.
Regards,
