[1] IISNA grew out of an earlier organisation which was called IISCA (Islamic Information & Support Centre of Australia).
When reconciliation between the two factions was shown to be impossible Abu Hamza withdrew from the organisation and brought his followers with him in founding IISNA.
[2][3] In 2007, Mohammed Omran was said to be the spiritual leader of the IISNA[4] and with IISCA (in 2009) being linked with the Ahlus Sunnah Wal Jamaah Association.
IISNA recently became involved with organisations in Indonesia, after giving support following the December 26, 2004 Indian Ocean Tsunami.
IISNA through support from the Muslim community of Australia raised funds to build an orphanage in the nation for Tsunami orphans.
In early 2010 it was announced that IISNA would build a new youth centre (MyCentre) based in Broadmeadows, Victoria in the heart of Melbourne's Muslim community.
