Last I read was that a decision was to be announced in third quarter of this year.
If it was to be earlier, historically there have been 'defence' equipment announcements around Budget time (May of each year).
So probably half a year away at least (and that doesn't leave much room to meet the planned 'cutting steel in 2018' schedule).
Don't know if that has been reported, see link below:

I read this on the ASPI Strategist site recently, the relevant quotes were:
The first paragraph regarding mission modules (future minewarfare? Hydrographic?) was interesting, "not in these 12 vessels".
Does that leave the door open for an expansion of the 'current' SEA 1180 fleet of 12 to eventually be more like the 2009 DWP 'planned' fleet of 20 ships?
And if these 12 ships are not equipped with mission modules, can they be 'retrofitted' in the future?
Lots of questions, not too many answers!!!
