In a statement, a spokesperson for CASA said Bonza needed “to demonstrate how they will integrate these Canadian-registered aircraft and crew members into their operation”.
“This is an important part of Australian aviation safety regulations,” the statement said.
Under Australian aviation regulations, operators must have “comprehensive safety systems” covering issues such as crew training and checking, maintenance and emergency procedures.
The Canadian-registered Flair aircraft are not part of the existing approval which gave Bonza the green light to start operations in January out of the Sunshine Coast.
