Wheeler,
You have identified one of the practical problems .... historically, Australian light aircraft manuals have put into the manuals the operational restrictions which the operator is responsible for in the US.
Whatever US manual you get for the new requirements is fine ... but you ought to give some consideration as to what safety fudge factors you might wish to apply in the real world use of the POH numbers ... if you still have the old P charts, there is nothing to stop your using them provided that they are conservative with respect to the US manuals ... as they almost always will be.
This is even a concern with the heavy manuals where the US practice is to present, for instance, landing data unfactored and then rely on, for example, 121 requirements to cause the operator to adopt the conventional fudge factors ....
Many traps for Australian players over the next few years until we have a few prangs and the message starts to filter through ..... suggest that people advance with caution in the matter of using US POH data ... the old paternalistic days of the Australian regulator's looking after us are GONE ..... we are now moving into the big bad real world where you are, to a large extent .... on your own.
One of the major concerns I have is in regard to the typical lightie pilot who routinely flys out of a nice long runway at, say, Moorabbin or Bankstown and then heads off bush and is faced with a critical landing/takeoff at a bush ALA or paddock ..... this is where mindless and uncritical use of the US data is going to bite and bite hard ...
It will be better when the harmonisation regulatory process catches up with itself ... if it ever does ..... but, at present, there are more than a few holes in the setup ..... please do be careful and cautious out there, good people ...
