Federal Member for Parkes Mark Coulton has been named as the Minister for Regional Services, Decentralisation and Local Government.
Prime Minister Scott Morrison unveiled the new cabinet on Sunday afternoon.
Mr Coulton, who will also remain as Assistant Trade and Investment Minister, said he was deeply honoured to have been appointed this new ministerial role.
"I thank the Prime Minister Scott Morrison and Deputy Prime Minister Michael McCormack for asking me to undertake these important roles," he said in a statement.
"As Member for Parkes, which covers half of New South Wales, I have worked hard to improve digital connectivity, and to bring more doctors to our rural and regional communities. As Minister for Regional Services, I will now be in a position to make even more of a difference to people's lives in rural and regional areas, which is a great privilege.
"Decentralisation is a significant part of what helps regions to thrive. I have long supported bringing more people and a diverse skillset into our regions, and as such I look forward to this area of responsibility."
Mr Coulton's key ministerial priorities are building on the Coalition Government's successful Mobile Black Spot Program to improve regional connectivity; improving the rollout of the NBN across Australia; and bringing more doctors and medical professionals to rural and regional areas.
He will be officially sworn in
Having been Mayor of Gwydir Shire Council prior to first being elected to the Australian Parliament more than 11 years ago, Local Government is close to my heart. As Member for Parkes, I have enjoyed working closely with local councils across my electorate, of which there are now 18.
"Thank you to those who have supported me since I was first elected in 2007 - I am excited about improving outcomes in the Parkes electorate and further afield in my new and existing areas of responsibility," Mr Coulton said.
"I look forward to receiving a brief from the outgoing Minister in due course, and getting straight to work."
