There are no general-issue Australian $50 notes dated 2008 that have any value above their face value. There is a very small market for notes that are in perfect (UNC) condition, however that is rather limited at present.

Although there was only one note printed with this full serial number, the serial range is not rare.

If it has been circulated but still in good condition, it might fetch anything from $22 to $40 AUD. A reputable coin dealer will be able to give a more accurate valuation.
Every serial number is as rare as the next, because every note has a different one.
