The trek was started by the former member of Farrer, Tim Fischer, in 1985.

It became famous and an annual event along the Hume and Hovell track in the Snowy Mountains before Mr Fischer became the Deputy Prime Minister and National Party leader.

The trek was resurrected by the member for Riverina, Michael McCormack, four years ago.

Mr O’Farrell took part in the walk for the first time last year.

He is returning to Tumbarumba where he received a warm welcome last year and enjoyed the tourist attractions in the Snowy Mountains.

“In addition to the NSW Premier, my Nationals’ colleague (Federal Indigenous Affairs Minister) Nigel Scullion will attend and take in the spectacular scenery along the Hume and Hovell track,” Mr McCormack said.

“I always look forward to this time of year.

“Tumbatrek is a great event which draws national attention to the beauty of the Snowy Mountains and attracts greater tourism and interest in the area.”

Last year’s walk started at the Tumbarumba council offices.

The distance and section of this year’s walk is still being finalised.
