From the picture, it looks like Cacatua sulphurea
The yellow-crested cockatoo (Cacatua sulphurea) also known as the lesser sulphur-crested cockatoo, is a medium-sized (approximately 34 cm long) cockatoo with white plumage, bluish-white bare orbital skin, grey feet, a black bill, and a retractile yellow or orange crest. The sexes are similar.[Source]
Habitat and ecology:
It mostly inhabits evergreen, deciduous, monsoon and semi-evergreen forests.
It nests in tree cavities or a pre-existing hole made by any another species.(Nandika et al.)
Observations made on Masakabing Island suggests that it's favourite diet include male fruits of Artocarpus communis, flowers and fruits of Cocos nucifera, Young leaves and flowers of Ceiba petandra, mangroves and male fruits of Brassus sudaica.(Metz et al.)
It mostly nests on C. nucifera, A. communis, C. petandra, Tamarindus indica and Avicennia sp. (Nandika et al.) [Source]
Why it is not Cacatua galerita?
I would say it's a sulphur-crested cockatoo (Cacatua galerita). It is a quite common pet bird.
