Mr Constance said the'Bondi link'service would be a"high-frequency,high-capacity bus service"that would add 1100 services and shuttle an extra 29,000 people along the 333 route each week.
"It will enable more than 1000 extra customers to get on a bus along Bondi Road during the morning peak alone. We will also boost capacity by 10,000 on the weekends for families and tourists visiting Bondi Beach."
An overnight bus on the route will operate all-stops between the city centre and North Bondi,seven days a week.
Mr Constance said the service would mirrorthe northern beaches' 'B-line' double-decker bus service that runs between Mona Vale and the city centre every five minutes during peak periods.
"Everyone has loved B-line,everyone is going to love Bondi link because of the very nature of the turn up and go service."
He said power lines along Oxford Street and Bondi Road meant the route had to be serviced by the bendy buses,drawn from the existing fleet,rather than double-decker buses.
