I was looking to see how much the $10 1988 note was as I've got a few sandwiched in books on my bookshelf somewhere. In the old Encyclopaedia which hasn't been opened since the mid 90s due to the internet.
I came across an auction: First prefix 1999 $100 Australia and is currently listed for $19.54 that'd be great to get a $100 note for $19.54 plus postage. Auction's here:
