Federal Education Minister Brendan Nelson has seen for himself the appalling conditions endured by Moss Vale High School students.

Mr Nelson viewed the school's two 19-year-old 'temporary' demountables and leaky school hall during a visit to the school on Friday.

Although public school spending is primarily a State Government responsibility, fed-up Gilmore MP Joanna Gash called in Mr Nelson to see if he could put pressure on the NSW Minister for Education and Training, John Watkins, to treat the school as an urgent priority.

The visit had the full blessing of State Liberal Member Peta Seaton, who has expressed her dissatisfaction over facilities at the school in the past which was threatening to undo great things happening inside classrooms.

Earlier this year, teachers learnt that the school had once again missed out on State Government funding, not receiving one cent from the Budget's $70 million school maintenance upgrade program.

When asked if she was stepping on State Government's toes by involving Mr Nelson in such a matter, straight talking Mrs Gash was typically blunt.

"I don't care, I just want to see this school fixed," she said.

"Of all the State schools in my electorate, Ulladulla and Moss Vale High School are lagging behind, not in teaching methods but in bricks and mortar."

Mr Nelson met with Moss Vale High School principal Jim McAlpine and P&C president Grace Avery to discuss a number of issues including the degraded courtyard, overcrowding, the demountables and run-down toilet facilities.

Mr Nelson admitted he was shocked by what he had seen and would be writing to Mr Watkins as a priority to see what action could be taken.

"There are obviously problems at the two schools I've seen today at Ulladulla and Moss Vale and I'll be writing to John Watkins to try and make these a priority," he said.

"I know Peta (Seaton) and Jo (Gash) have been working hard on this and I'll try and move things along better by beating the drum."
