At Brighton, contact Moorabbin Tower on 123.0, the western frequency. Descend to enter the MB CTR at 1,000 ft unless instructed otherwise. ATC may track you via Moorabbin Oval. Exercise caution with opposite direction traffic departing Moorabbin, tracking north to Albert Park Lake or Brighton on climb to 2,000 ft.
Normal procedure for helicopters is to track inbound coastal via Cerberus. Helicopters can approach direct, without going coastal, but this requires caution as it could potentially put you at the same level as inbound fixed-wing traffic arriving via Brighton, on descent from 1,500 ft to 1,000 ft in this area.
