Narrative:

Initial clearance was to taxi to runway 30L via taxiway C, hold short of runway 4. Subsequently cleared to cross runway 4, continue taxi to runway 30L. After crossing runway 4 on taxiway C, I completed the takeoff data for runway 30L. While computing the data, I failed to notice that the aircraft was now on taxiway K and just entering runway 30R. Ground was immediately notified of the occurrence and cleared us to taxi south on runway 30R to taxiway left then rejoin taxiway C and continue to runway 30L. The captain called ground control on the telephone when we arrived in aus. ATC reported there was no conflict and the situation was ok.
