The man heading the national disability insurance scheme agency says it needs to be governed effectively if it is to succeed.
NDIS agency chair Bruce Bonyhady for the first time addressed the controversy surrounding the government's decision to replace the board overseeing the $22 billion scheme.
Positions for directors were advertised nine months before contracts for existing members expire next year, a move criticised by disability groups concerned it will prioritise corporate experience over lived experience with disability.
Mr Bonyhady, regarded as one of the key people behind the scheme's birth, could lose his position at a time when the agency prepares to reel in more than 400,000 people into the NDIS.
He said the new appointments were a matter for government and he was only focused on doing the best he could while still in the job.

"This is a very, very important scheme, it needs to be governed as effectively as possible."
