Two of Australia’s biggest banks, National Australia Bank and the Commonwealth Bank of Australia, will dramatically increase the size of their Indian operations, cutting down their reliance on external IT suppliers to build a bigger army of internal tech stars on the subcontinent.

NAB is poised to add up to 3000 staff to its Indian operations – which hints at problems for suppliers such as IBM, Genpact and Infosys, which currently provide significant numbers of workers for the bank in India – as it plans to conduct higher-value work in its offshore innovation centre outside of Delhi.
