The councils, government agencies and rail corporations responsible for managing fire risks along the Olympic Highway are evaluating what measures are needed as the weather heats up.
However, issues around traffic management and terrain will put some limits on what can be done to reduce hazards around roadside and rail line vegetation.
Roadside vegetation along the the Olympic Highway, which also runs parallel to the Main South Line railway out of Wagga, divided up between the NSW Roads and Maritime Services or the federal Australian Rail Track Corporation, and councils.
A Wagga council spokesperson said there was an assessment made of roadside vegetation and its management "at the start of each fire season".
"Strategic roadsides and Asset Protection Zones identified by the Rural Fire Service are mown by council and council contractors on a schedule in accordance with the RFS's requirements and the seasonal conditions," the spokesperson said.
"These areas are then monitored and managed when deemed necessary depending on the season and growth.
"All other parks and reserves within the LGA which are maintained by council are managed on a four-week maintenance program. This is also weather dependent."
Greater Hume Council environment and planning director Colin Kane said large roadside trees could limit options for fire risk management.
"For the Olympic Highway we slash 1.5 metres behind the guide posts and if possible we will go further," he said.
"Beyond that distance we cannot undertake fire control measures due to the nature of road reserves that contain significant native vegetation".
In December last year, a malfunctioning freight train ignited grassfires along five kilometres of rail corridors at Uranquinty.
Both the rail line and the highway were closed as firefighters responded to the incident.
An ARTC spokesperson said the corporation managed a rail network covering 8500 kilometres.
"So if there are locations that are a specific concern, we're happy to respond to requests by local residents and councils to clear vegetation that's grown rapidly or needs attention," the spokesperson said.
"ARTC works with local road authorities including RMS to ensure vegetation along the Olympic Highway is safely managed."
Transport for NSW Director South West Lindsay Tanner said responsibility for roadside vegetation along the Olympic Highway was shared between the state government and councils.
"Transport for NSW maintains vegetation for the safety of road users by slashing and spraying road shoulders and maintaining vegetation in drains next to the road to allow water flow," he said.
"The relevant local council is responsible for property and vegetation outside the road shoulders.
"Transport for NSW's Bush Fire Hazard Reduction Work Procedure details the framework for assessing the potential environmental impact of bush fire hazard reduction work carried out in the road corridor and on Transport for NSW owned, controlled or managed properties and infrastructure."
