There was a DMO "minors" project to equip all 3 of these vessels with 4x 25mm Typhoon weapon systems each. Mini-Typhoon was to equip the vessels as an "interim" capability.
Funny. I just did my homework on this matter and look what DMO has to say about it now...

Ships Self Defence Capability – Rapid Acquisition
Phase 1 of SEA 1779 Ph 1 will provide a dual level ship self defence capability for HMA Ships Kanimbla, Manoora and Tobruk.
This capability will provide better defence against watercraft, land targets, helicopters and floating mines. The capability will consist of an integrated fire control system and Toplite electro-optical director system. The 25mm Bushmaster naval variant cannons are to be integrated to provide the cannon for the Typhoon system.
The “fit for but not with” installation schedule is on track, however the procurement of hardware and in particular Typhoon mounts lag by 6 months. Notwithstanding, TOBRUK, KANIMBLA and MANOORA are presently configured for Mini Typhoon Self Protection, albeit KANIMBLA will have the Mini Typhoons resited at the next Availability in May to pave the way for the installation of Typhoon mounts on delivery from Rafael Feb 09, to provide the optimal self defence capability.
Initial Operational Release of the first ship with optimal self defence capability is scheduled for February 2009, with project completion in July 2009.

I imagine given the "lag" mentioned above, along with the FFG-UP issues with the Rafael provided C-PEARL EW system that Rafael are almost as popular as Boeing within the DMO and larger DoD these days...
I'm starting to wonder if there are there ANY projects that come in on time, that aren't FMS based?
