"So today's mortgage brokers provide customers with a valuable service by being largely used by customers," said Mrs. Wikramanayake.
"We think they provide competition and service, and that's important [we] Try to continue [this].
"The way they are rewarded, they have to change how they can engage with their customers, they have to change, but I think the service they provide is valuable to customers so they will have to stay."
Ms. Wikramanayake introduced her comments after the operating briefing, confirming the guidelines for profit growth of up to 15 percent from last year's $ 2.56 billion, indicating that it is on the way to making a profit of up to 2.94 billion dollars for the current financial year , which ends in March.
The bank has also updated the market for regulatory issues, including a German investigation into the alleged tax fraud scandal. Ms. Wikramanayake said that the authorities in Germany formally classified 22 former and existing bank employees as "interested or suspect", including himself and the predecessor of Nicholas Moore.
This was expected, and the bank said in September that employees could be classified as "suspects or suspects" under German law to be interviewed.
Ms. Wikramanayake also said that the bank "carefully follows" the implementation of the Haynes Royal Commission's recommendations.
"The Royal Commissions are always valuable processes for any industry, they have strict control and our opinion is that we are able to learn and change in relation to anything," he says.
Macqaurie's market presentation has highlighted the opportunities it has pursued in the industries, including renewable energy, real estate, conventional industry and infrastructure, in various markets around the world.
Ms. Wikramanayake said that the idea behind her diverse range of businesses, including fund management, investment banking and loans, is that revenue would be less volatile.
Macquarie Group shares, which rose 23 percent last year due to strong demand for infrastructure and renewable energy investments, reached 2.15 percent to $ 124.60.
