Anna Speedie said she had spoken to state Regional Development Minister Jaclyn Symes on Thursday and received a copy of a letter showing Victoria supporting the Albury-Wodonga deal.

The announcement follows a Senate estimates hearing on Monday being told by a Commonwealth mandarin that state governments needed to give their approval for the federally-funded deal to "accelerate".

"I got a copy of that (ministerial letter) yesterday and I spoke with the minister, so we're absolutely delighted," Cr Speedie said.

"It means that we can get on and get cracking on all that strategic work that we need to do in and around regional planning for the next decades."

However, member for Albury Justin Clancy said the NSW government was yet to finalise its commitment.

"My understanding is that state and federal agencies are working through and it's certainly progressing and it's been constructive but we haven't been given a definite time when things will hopefully be completed," Mr Clancy said.

The backing of the states will allow $3.2 million to be released by the federal government for 12 months of detailed planning on what Border authorities want to achieve from the deal.

The announcement by Cr Speedie came as her counterpart, Albury mayor Kevin Mack, was in Townsville for a conference of the International Cities, Town Centres and Communities Society.

He addressed the event on Friday on the topic Two Cities One Community: An Innovation in Collaboration.

Cr Mack did not respond to The Border Mail on Friday.

However, an abstract for his talk noted "the two cities had a long history of competitiveness and poor collaboration" and "through the leadership of the two mayors, the cities have embarked on a mission to work together to achieve their goals now and into the future".

Cr Speedie said she was invited to the forum along with Cr Mack but declined due to other duties.
