He welcomed an ongoing commitment to upgrading Dubbo Hospital and the establishment of a special-needs school in West Dubbo.

"Also, the bridge renewal program, Newell Highway upgrades, money set aside for airports, that's all good," he said.

"In fact, this $95 million that's been earmarked for regional airports, Dubbo's been shortlisted and we need to make sure we get a submission together that really stacks up to get a share of that to grow our region."

There was one area Mr Walkom would have liked to have seen the government place a greater emphasis upon, he said.

"Relocating government departments out of Sydney, that would give regional communities a boost and benefit people looking to live and work in regional Australia," he said.

The network-specialist school to be established in West Dubbo was designed to support students with disabilities or who had other special needs, Dubbo MP Troy Grant said.

It would directly link the surrounding schools and families with government and non-government specialist services across health and community services.

"Dubbo West Public School will also benefit from this project and this is a great benefit to the community," Mr Grant said.

"The provision of four new state-of-the-art classrooms and a new preschool facility are to be built on the Dubbo West Primary School site.

"This will allow the primary, infants and preschool to be located on the one site with many educational and social benefits for the students."

Further west, some $2.8 million would go towards a $3.27 million project upgrade for Brewarrina Central School and $4.77 million for an upgrade of Walgett Community College.

Dubbo MP Troy Grant said the budget was his first as Deputy Premier and he was "enormously proud" of it.

He said everything promised was being delivered.

"It's locked and loaded," he said.

Mr Grant said police officers in Dubbo and surrounds would also benefit from a $100 million crime-fighting technology fund announced in the budget, designed to allow them to spend more time on the beat.

They would be equipped with technology such as tablet computers for frontline officers, enabling them to access police computer data in the field, mobile fingerprint scanners that would allow instant identification of offenders and TruNarc testing machines to allow police to scan for multiple narcotics using a simple hand-held machine.

Mr Grant said it was important police in the regions who travelled vast distances to respond to crimes had better technology out on the road.

A further $3.47 million of the $16 million Walgett Police Station project would also be forthcoming in 2015-2016.

The budget also included a further $8.4 million for Dubbo Hospital stages 1 and 2, which Mr Grant said was "on schedule" for completion about October, after which planning, design and early works would commence for stages 3 and 4.

Some $32 million had been earmarked for ongoing road maintenance in the Dubbo electorate, Mr Grant said. Specific road projects included $1 million for planning the duplication of the LH Ford Bridge in Dubbo.

Realignments to the Mitchell Highway at Guanna Hill and the Newell Highway at Trewilga had attracted $7 million and $5 million in funding respectively. Some $2 million had been earmarked for a Newell Highway upgrade at Parkes.

Some of the 2015/16 allocations for roads included $9.8 million for road and bridge maintenance, $2.7 million for pavement upgrade on the Newell Highway 35 km north of Peak Hill, $1.5 million in block grants funding to Narromine.

Council for road maintenance, $1.2 million in block grants funding to Wellington Council for road maintenance and $1 million in block grants funding to Dubbo City Council for road maintenance.

There would also be $950,000 for pavement upgrades on the Golden Highway 50 km east of Dubbo, he said, $800,000 towards pavement upgrades on the Mudgee-Wellington road, $2.7 million towards the installation of railway boom gates at the Victoria St and Mitchell Highway intersection, the Sheraton Road level crossing and the Yarrandale Road and Wheelers Lane level crossings, along with $510,000 for road sealing and clearzone widening at Mookerawa.

The budget also provided $7.5 million to start replacing the 30-year-old XPT fleet.

"Dubbo will be a major beneficiary, with better timetables, a better experience and shorter trips," he said.

"There'll also be safety upgrades around railway lines, money for the Golden Highway, a big upgrade for the Mitchell and Newell highways," Mr Grant said.

More than half a billion dollars was earmarked for water security across NSW, including 16 local infrastructure projects and an initial $52.3 million to secure emergency water supplies for Broken Hill as part of Restart NSW.

Western NSW would get a share of the $38 million allocation under the Country Towns Water Supply and Sewerage Program, which provided financial assistance to councils to upgrade water and sewerage infrastructure. That included $2.2 million for the Walgett water supply bore.

Money was also earmarked for the North Macquarie Marshes Refurbishment initiative, the Warrumbungle Rehabilitation Program and to fishways downstream of Burrendong Dam.

The government also committed $2,781,000 in 2015-2016 for the visitor experience at Taronga Western Plains Zoo and $765,000 for construction and restoration projects there.

The budget also included funding for new land and a new Fire and Rescue NSW station at Nyngan.
