Run by Huntsman Recruiting's Rhyley Hunter and Kaity Fuller, the regular web-chat is will be in its sixth and final week when the two international heavy-hitters drop by from 7pm on May 27.

"We've been calling it the 'strange times' webinar series, and we set it up to educate and keep things positive during these strange times we're living in," Mr Hunter said.

Previous guests have included Riverina-based entrepreneurs Belle Armstrong and David Kapay, the deputy prime minister Michael McCormack, state members Dr Joe McGirr and Justin Clancy, among others.

"We've had some political voices, we've looked at leadership, mindfulness, positivity, and we thought for our final one, why not go for someone high profile," Mr Hunter said.

"It took a little tracking down, but we kept knocking until [Julie Bishop and Lisa Messenger] accepted."

Mr Hunter admitted he didn't fully expect the former deputy Liberals leader and current chancellor of Australian National University, Julie Bishop, to accept the offer.

"We thought we'd be cheeky, it was an unreasonable request but we thought we'd make it anyway," Mr Hunter said.

"We were surprised when they both got back to us and said they'd do it together."

In weeks gone by, the webinar series has streamed live to between 30 and 100 virtual guests.

But in the lead up to the final week, 150 have already registered. Mr Hunter expects it will be viewed by up to 500.

"We try to make it fun and relaxed, and just get to know them a little," he said.

"Have a wine, tune in and see a bit of their sense of humour."

Registering for the virtual event can be done via the Huntsman Recruiting Facebook, Instagram or LinkedIn pages.
