Incriminate numbers with in alphanumeric string

Hello Experts,

All data are in one column starting cell are A1,A2,A3,A4,& A5 and so on
task to me is increase numbers in between string in the following manner :-

AUSY/200214/0001/01
AUSY/200214/0002/01
AUSY/200214/0003/01
AUSY/200214/0004/01
AUSY/200214/0005/01

currently I copy A1 up to required say 30 cells and change manually...

any suggestion/assistance appreciate,
Thanks in advance

Maybe...

="AUSY/200214/"&TEXT(ROWS($A$1:A1),"0000")&"/01" and copied down

Type formula in cell a1 = "Ausy/200214/"&"000"&rows ($ A$1:A1)&"/01"

Hi Azumi & Thameem127,
Both suggested functions works brilliantly!
Thanks a lot for solutions
