The Canberra Liberals have endorsed Peter McKay as a candidate for Kurrajong for this year's ACT election.
The party was forced to find a new candidate when pre-selected candidate Vijay Dubey pulled out in July.
Mr McKay ran for the Liberals in Kurrajong in the 2016 election.
He was born in Queensland and has lived in the area for the last 33 years with his wife, Trish.
He has been an army parachutist, career army officer including commanding a tri-service overseas contingent, an executive level public servant, a union delegate and an army reservist.
He has also been a commercial property owner and secretary to a unit body corporate that prosecuted a builder for building defects.
"As a Canberran by choice who has lived, worked and raised a family in Canberra, I want to make sure that Canberra is the best place for my kids and grandchildren to raise their own families," Mr McKay said.
"Old governments get cosy and stale. It's time for a change so that we can improve the deteriorating response times in our health system."
Mr Dubey was told he would be disendorsed if he did not resign in July following weeks of growing tensions between the former candidate and senior party officials.
Mr Dubey did not provide an explanation for his resignation. He previously told The Canberra Times his candidacy was "all history to me".
