The state government of Victoria has appealed to its Victorian teachers to accept its latest and final counteroffer of 2.5 per cent a year pay rise over three years plus extra for productivity gains if only to put an end to their long-running industrial dispute as well as to avert the planned mass work stoppage by the teachers on April 30.

"What we've done now is put a full and final offer on the table with the teachers," Victorian Premier Denis Napthine told Fairfax Radio on Tuesday.

"I would urge the teachers' union, indeed all the teachers, to accept this very positive offer from the Victorian government."

But the members of the Australian Education Union said they were far from happy with the offer since from the original 30 per cent over three years first lodged in 2012, they have since reduced this to 12.6 per cent over three years in November 2012.

"We do not take industrial action lightly, but in this case we must keep fighting, it is crucial to ensure quality teachers, principals and education support staff remain in this state and in our profession," Meredith Peace, the union's state president, said.

The scheduled April 30 industrial work action by the teachers is the first in a fresh round of half-day regional stoppages statewide.

"We have been negotiating for over two years and there are still a number of outstanding issues to be resolved, including salaries, workload, class sizes and the high level of contract employment," Ms Peace said.
