Adrian Pederick will aim for a fourth term in parliament at the 2018 state election after winning Liberal Party preselection for the electorate of Hammond.
No-one challenged his nomination for the preselection, so a vote of the 200 or so local party members was not needed.
Mr Pederick took that to mean he had the confidence of the local branches and, by extension, the community.
"I work hard, I don't treat the seat as a so-called safe seat, and I've got a very good staff behind me; we work with a resolve to serve the community and get the job done," he said.
"It's up to the community to judge that, and at this stage of the process it's up to the members of the Liberal Party in Hammond.
"I see that as a reflection on community sentiment, to a degree."
He said he had not expected anyone to challenge him, but "you never know until nominations close".
As the Liberal candidate, Mr Pederick will be a short-priced favourite to continue as the Murraylands' spokesman on North Terrace.

The political challenge ahead, then, will be helping the Liberals win government on March 17, 2018.
He believed Opposition Leader Stephen Marshall's team, with a mix of experienced and new candidates, was ready to govern South Australia.
Mr Pederick has represented the Murraylands on North Terrace since succeeding independent MP Peter Lewis in 2006.
He has done so alongside the members for for Schubert, Stephan Knoll; MacKillop, Mitch Williams; and Chaffey, Tim Whetstone.
But the electoral boundary changes will remove Mannum from Mr Knoll's electorate and Karoonda from Mr Whetstone's in 2018, and add both to Hammond.
Mr Williams will retire at the election; Liberal candidate Nick McBride hopes to succeed him as the MP for Meningie and the upper South East.
