Surfside has standardised on Bustech bodywork in recent years and 537 (MO4542) is one of several Hino RG230 bought in 1999 with 57 seat bus bodies.
South of Burleigh Heads is a Bustech single door Mercedes O405NH, 599 (599FIB - honest!).
Nearest the camera, leaving Pacific Fair, is another Mercedes O405NH Bustech, 635 (101GWD). Heading for Burleigh Heads is seemingly identical 826 (826GTL). Both date from 2002, but 826 is a Volvo B7RLE.
