it is likely that JQ will recruit second officers in the not too distant future. These would be for the longer B787 international sectors such as Sydney or Melbourne to Hawaii and Japan. There are a few unsubstantiated rumours circulating of other possible destinations in future also. At the moment this role is being done by an additional FO or occasionally another captain as relief pilot.
The new JQ EBA just negotiated has the second officer position included.
Good luck
