But other cross-border issues still remain without a solution.

The map in the "fires near me" app showed December and January's Upper Murray bushfire stop at the border with Victoria, not allowing users to track the blaze as it jumped back and forth across the state line.

NSW Rural Fire Service Commissioner Rob Rogers said the app upgrade will allow users to track fires on the other side of the border.

"There's an ability to get warning zones and put those warning zones on 'fires near me'. There's a lot of building on lessons learned from that fire season," he said.

"It's ensuring we have consistency of data and taking feeds from (Victoria's) app to ensure we can display it.

"What we're notionally thinking is (displaying bushfires that are) 50 kilometres outside of NSW into another state, so people can see fires if they're coming."

Asked if he believed fire services should take a more national approach to bushfires, Commissioner Rogers said jurisdictions had worked well together for many years.

"We work very closely with our colleagues," he said.

"Apart from the reporting of fires through the various apps, I haven't actually heard of any other concerns through borders."

But in a joint submission to the same bushfire inquiry, Albury MP Justin Clancy and Benambra MP Bill Tilley pointed out other cross border issues, including the fact that NSW and Victorian firefighters could not communicate with each other using incompatible radios during the summer bushfires.

"This leaves the crews exposed to unnecessary additional risks," they said in the submission.

Asked about NSW and Victoria having different warnings systems, which has also been raised in the Royal Commission as a problem, Mr Rogers turned the focus back onto Victoria.

"Victoria didn't adopt the national standard, which was the (term) 'catastrophic' - they went with 'code red'," he said.

"Everyone else went with what was agreed nationally."

Psychologists will be hired for each of the Rural Fire Service's seven areas commands, including the south western zone that includes the Albury and Wagga offices.

RFS Commissioner Rob Rogers welcomed the appointments, which will be funded as part of $36 million for a new first responder mental health strategy.

"They'll be able to really quickly work out who needs that support, make sure they get the appropriate referrals, manage them until they get to the best place they can be," he said.

"It's a big game-changer for RFS."

Other features of the funding package, announced in response to the NSW bushfire inquiry, included $23 million for new personal protective clothing for firefighters and $17 million to retrofit hundreds of RFS vehicles and replace Fire and Rescue NSW tankers.
