Your second note has a couple of Asian moneychanger's stamps on it. It's not a misprint. No extra value.
The first note has an unusual number, but I don't think it's a number that a collector would pay much of a premium for. It's not a solid, repeater or radar, in either six-digit or eight-digit format. (for those unfamiliar with Australian notes, the first two digits are actully the date: 2009 and 2008, for these two notes, so they don't technically count as part of the "serial number").
As for grade, I think gVF to EF would be reasonable.
