Opposition Leader Will Hodgman and opposition education spokesman Michael Ferguson yesterday were at Triabunna, which would be one of the first towns to be affected by the policy.

"In coming months we will be identifying more rural and regional communities, including some in the North, that a Hodgman Liberal government would look to have a discussion with about their local high school being among the first to extend to year 12," Mr Ferguson said.

"Retention is a statewide issue and we believe extending high schools to year 12 is a key part of the solution."

The opposition has committed to extending Tasmanian high schools to year 12 within its first decade of office.

Mr Ferguson said Triabunna had been chosen as one of the first towns to be involved because it was a community under threat due to the woodchip mill closure and because of residents feeling uncertain about the future.

"Services are the key to keeping regional and rural communities strong," he said.

The opposition would consult relevant communities and would not take a one-size-fits- all approach, Mr Ferguson said.
