An Australian 1982 One Dollar note (Johnston/Stone - serial DNB), uncirculated and in absolute mint condition could fetch anything up to $7 AUD. If it has been circulated but still in good condition, it might fetch anything from $1 to $3 AUD.
A reputable coin dealer will be able to give a more accurate valuation.
All Australian banknotes have a serial number. For each issue of banknotes, there will be a first and last serial number. The Australian paper Fifty Dollar note issued in 1973 with the signatories Phillips/Wheeler, had a first serial number of YAA 000000. The last note printed in that series had a serial number of YAU 999999. The next series of Australian paper Fifty Dollar note issued in 1976 with the signatories Knight/Wheeler, had a first serial number of YAV 000000. The last note printed in that series had a serial number of YBX 999999. Banknotes with first and last serial numbers usually have a higher collector value.

For a valuation on Australian banknotes, you would need to provide the serial number and the signatories on the note, the condition and any peculiarities.
