"It was with shock and sadness that I learnt of the sudden passing of Don Randall, the Federal Member for Canning," Prime Minister Abbott said.
"On behalf of the Government and the Liberal Party, I convey my condolences and deepest sympathies to Don’s wife Julie and their two children.
"Don was an outstanding local member. He was a passionate and persuasive advocate in Canberra and a hardworking community leader in Western Australia.
"He was first elected to the House of Representatives as the local member for Swan in 1996. He was elected as the local member for Canning in 2001 and re-elected in 2004, 2007, 2010 and 2013.
"Don made a fine contribution to the Howard Government and particularly to the Coalition during our years in opposition.
"He was a mentor to many and integral to the success of our Party in the state of Western Australia.
"He served the Party for many years prior to his election to Parliament including on the state executive.
"It’s hard to credit that this strong voice for Western Australia and servant of our Party has left us so soon.
"All his colleagues will mourn his passing and honour the contribution that he has made."
Premier Colin Barnett issued a statement on behalf of the parliamentary Liberal Party.
"I am shocked and saddened by the sudden passing of the Member for Canning Don Randall," he said.
"Don was a very committed local member who worked hard for his constituents.
"We extend our deepest sympathy to his wife Julie and his family."

City of Mandurah chief Mark Newman announced the sudden death of Mr Randall at a Council meeting on Tuesday evening.

"It's quite sudden, particularly for those who saw him at lunch time at our turning of the sod ceremony.
"We'll obviously gather our thoughts and release something that's appropriate to say about Don Randall's achievements.
