Hand written cache-notes perhaps?

Now This one looks like it might be a clue to a new puzzle cache.... But alas it was written long before GPS was even thought of.
it is from the handwritten manuscripts exibition ithat was recently in Canberra.

the Shifters have written...
A quick hello from Canberra on our weekend of culture at the Handwritten manuscripts and Renaisance paintings. Hopefully a cache or three. regards,
