300mAUD is about 186m GBP at the moment, a far cry from the original contracted total cost for 4 Bay Class which was 300m GBP. ie 75m GBP each [c2000AD].
Whether the Largs Bay represents value for money [at whatever the final offer is] depends on the needs of the purchaser and I doubt that the publicity surrounding our 'urgent' sealift needs has helped reduce the asking price to oft mentioned "fire sale" level.
Trying to work out what the British project should have cost, compared to an unproblematical new build, is next to impossible for a layman. I'm hopeful the RAN would have a good idea on that figure though.
The article linked below lists many problems/costs which more reflect ineptitude on the lead shipyard than the build costs at BAE. Even so, BAE added millions to their final costs due to delays from Swan Hunter.

Both ships built at Swans had problems, Largs was launched in 2003 and much delayed in finishing. The Swan Hunter yard closed down after her sister ship [Lyme Bay] was removed to BAE for finishing.
The Brits were lucky in that they had two yards building the same class, some Bays may have joined Nimrod. What did the ships cost the Brits? A whole lot more than they should have!
When it comes to what Australia should pay, providing the ship is squared away, none of the above means anything really. What counts is the need of the purchaser, compounded by the time constraints of any alternative to servicing that need. Both have varying dollar values. The more pressing the need, the higher the asking price, usually.
A Bay Class, new or a used, can fulfill the capability part of the need therefore, as AD has suggested, time is a major factor.
Can we afford to wait to build one or what will/could it cost us if we don't have the capability in the meantime? This is the crucial equation [IMO] that will determine how much we're prepared to pay, not the murky and obscure build costs of the original project.
I doubt anyone in the public domain has any real idea of the price being negotiated, I just hope it's good value for money.
