This accident and the Kempsey bus crash eight weeks later were described as "arguably Australia’s most catastrophic examples of high consequence/low probability incidents in the bus industry" in a bus safety discussion document. The response to these incidents was an effort in Australia, and particularly in
New South Wales, to better regulate the heavy transport industry. This included banning "stay-awake" drugs, limiting uninterrupted driving time and mandating rest periods. The design standards of long-distance buses and their safety equipment were also reviewed. The bus involved in the accident belonged to
Sunliner Express. The coroner's report cleared the bus of any responsibility for the accident. The bus company was liquidated in 1991 and the owners later founded
Transit Systems in 1995. The crash also prompted a proposal to upgrade the Pacific Highway to a divided road all the way between
Sydney and
Brisbane. The section of the Pacific Highway where the collisions occurred was bypassed in May 2020 by a dual carriageway as part of the Pacific Highway upgrades, and is now named
Big River Way. There is a
memorial to the travellers involved in the Grafton Bus Disaster located on a now closed-off section of the old Pacific Highway at Cowper. ==References==
