Kapundaite is a rare phosphate.

At the type locality, Tom's Quarry, Kapunda, Mount Lofty Ranges, South Australia, kapundaite occurs as linings within cavernous masses of an iron-rich phosphate rock (AJM 17.1.18). It is associated with natrodufrénite, meurigite-Na, leucophosphite (Mindat, AM 95.754-760), wavellite and mitridatite; fluellite and minyulite are rare associates (AJM 17.1.18).
