Alaedine Rifai, 40, also known as Alan Rifai, who is the director of kitchen joinery business Universal Group Australia, is charged along with his partner, Amal Hilmi, 35.
Her two brothers Mostafa Hilmi, 30, and Alhassane Hilmi, 27, who is the registered business name holder of Reliance Disability Services, are also charged.
All four were arrested after Australian Federal Poice seized luxury cars including a Porsche Cayenne, an Audi A3 and Mercedes E63 and other goods in a sting, which alleges they defrauded the National Disability Insurance Scheme (NDIS) of $1.1m.
Australian Federal Police allege three companies made fraudulent claims from more than 70 people on NDIS disability plans or the people managing their affairs.
Represented by three lawyers, the four accused requested to apply for bail on Friday but the release applications have been set down for June 4."
