On 2 February 2004, 20 Irisbus Agora Lines (Bus 300 – Bus 319) entered service with ACTION.
The Agora Lines were the first new buses in the ACTION fleet since the last Dennis Dart in February 1998 – a gap of six years. They were originally built in 2002 and 2003 for King Bros Bus Group (Kempsey). Prior to entering service, ACTION modified the vehicles by replacing the pink-coloured stanchions with stainless steel and installing a luggage rack in place of the front seat. However, the single door configuration was not altered, making them the only full-length buses at ACTION without a rear door.
These buses were ACTION’s first Custom Coaches CB60 bodies and they also marked the commencement of the 2004 ACTION green and white livery as well as being the first buses to be fully air-conditioned.
In 2015, the first Agora Line was withdrawn from service when Bus 300 suffered an engine fire in Spence.
