High Wycombe is served by Transperth bus services, operated by Path Transit and Swan Transit. Before the Airport Line opened on the 9th of October 2022, routes 296 and 299 provided the primary service for High Wycombe, operating to Elizabeth Quay Bus Station in the Perth CBD via Great Eastern Highway, or to Kalamunda bus station in Kalamunda, a regional centre of the Perth Hills. Route 296 served the centre of High Wycombe, whilst route 299 operated along Kalamunda Road, serving the northern part of the suburb. During the peak commuter period in the peak direction of travel, route 299 was replaced by route 295, operating limited stops along Great Eastern Highway, and route 296 was supplemented by route 298, which additionally served a greater area of the west of the suburb and travelled to Elizabeth Quay Bus Station via Shepperton Road.

Alternate, less frequent bus routes provided connections to railway stations and shopping centres in the Eastern metropolitan region. Route 294 operated to Midland railway station and Midland Gate shopping centre, or to Cannington railway station and Westfield Carousel shopping centre. Route 304 provided an off peak service to Midland railway station from Hillview Village, a retirement community in the west of the suburb.

As part of the Airport line, High Wycombe is now served by High Wycombe railway station. It was originally scheduled to be completed in 2020 but, after numerous delays, due to flooding, a sinkhole, and slower than expected borers, the opening was pushed back to the latter half of 2021. That was further delayed until 9 October 2022. The new rail line provides a 20-minute travel time to the Perth CBD, as well as a 2-minute travel time to the Perth Airport. High Wycombe Station is served by many new bus routes which improved service for the suburb. Route 280 acts as a partial replacement for the southern section of route 294, providing the connection to Cannington, whilst routes 277 and 278 now connect to Midland, replacing the northern part of the 294. Routes 275 and 276 replaced the 295/299 and 296 respectively, operating on the same alignment to Kalamunda Bus Station after departing the station, and providing a more frequent connection throughout the day. Finally, routes 270 and 271 provide connections to Forrestfield and onto Belmont and the Perth CBD by bus. Route 293 operates to Redcliffe station via Belmont, partially replacing the old 298 route.
