The pair, who grew up on a dairy farm just outside Rochester, arrived at the house of their late father on Echuca Rd to begin the clean-up on Monday afternoon.
“He died in 2019 and our stepmother, Margaret Iddles (Anderson), has been living in the house,” Barry said.
The house of the twin brothers’ sister, Nancye Lees, has also been severely affected by the flood.
They were planning to assist her where they could once they had finished on their father’s home.
The brothers were being assisted by Margaret’s son and grandson, John and Sam Anderson.
"About 18 inches of water has gone through the house,“ said Barry, who operates a large catering company in Queenscliff.
They contacted Rochester Business Network president Glenda Nichol to inform her they would be in town and would like to help out where they could.
“Once they have finished the clean-up at their house they have told us they will help anywhere they can,” she said.
Mrs Nichol was with the pair when they were removing furniture and were about to rip the carpets up in the home.
“They will also be putting on a sausage sizzle for the community later in the week in Iddles Lane,” she said.
A mural honouring the family was launched in March 2020 and has become a major tourist attraction in Victoria.
Ron Iddles is widely recognised as “Australia’s greatest detective’’, having a 99 per cent conviction rate in a career that spanned 43 years of investigating serious crime.
He took up the role of secretary of the Police Association of Victoria in 2014, retiring in 2016, before being lured out of retirement the following year to serve as Victoria's inaugural Community Safety Trustee.
In 2015, Ron was made a Member of the Order of Australia for services to the community.
The Iddles brothers were educated at Echuca Technical School and after finishing, Ron joined the police academy at 18 years old.
His current role involves him managing funds for community safety.
Ron was the subject of Justine Ford's 2017 book The Good Cop and he played the lead role in a Foxtel series in 2019, where he earned a Silver Logie (Logie Award for Most Outstanding Factual or Documentary Program) for the show.
