The webinar, entitled An Evening With a Local Statesman, is being compiled by Historical Society archivist Kim Bagot-Hiller [who is also Chifley's great-great niece], and will also mark 85 years since the former prime minister entered federal parliament.

Ms Bagot-Hiller said the scheduled date for the webinar [July 16 at 6.30pm] is also significant to the occasion.

"July 16 is the date Ben came back to Bathurst after becoming prime minister to see his brother, Dick Chifley, who was ill with a serious heart condition," he said.

"No one knew he was coming back to Bathurst, and the mayor at the time was planning a public presentation and parade to honour his ascension to the prime ministership."

Ms Bagot-Hiller said the webinar will investigate Chifley's connection to Bathurst, including his role as a railway engine driver, his link to local rugby union, his family connections and his extended role in the community.

"It won't delve too much into the political side of things but more so who he was to Bathurst, which I feel is something that needs to be brought out more," she said.

"We of course have Chifley Home and his statue on Commonwealth Street, but I'd love to see families get together around the computer to listen to this webinar, just like 1940s families would do with their radio."

Chifley was once described as the 'Abraham Lincoln of Australia' by famed American author and political activist Helen Keller.

Charles Sturt University [CSU] history academic and Chifley consultant Sam Malloy has assisted Ms Bagot-Hiller in compiling the webinar, and said it's important for descendants of significant historical figures to have a key role in the documentation of their history.

"When you think of overseas museums of prime ministers and presidents, they really try to include descendants to be involved in the storytelling and education process," he said.

"I've always admired Kim's inclusion of the extended Chifley family into deepening the local legacy of Ben and his wife, Elizabeth."

Councillor Jacqui Rudge said it's important for the community to be aware of Chifley's unique local legacy.

"Kim has such a remarkable compilation of research on the Chifleys and through her, I've learnt so much about Ben, Elizabeth and the extended family that I never realised," Cr Rudge said.

"I echo Kim's view that this webinar will provide plenty of value for Bathurst families, as it's important for residents to understand the community's history and heritage."

The event is free, and registration is open through Eventbrite.
