The 1 pound note is worth around $25-30 in that condition if you are lucky and the $1 (JG Phillips / RJ Randall 1969) I would say $10-$12. This is just my guessing.
In Australia, all banknotes issued since 1901 can still be redeemed at the central bank. For the 1 pound note, it is worth face value A$2.
I do not have either of the notes in my collection.
