The show hosted by the former Today Tonight entertainment reporter will feature “the hot issues of the day with lively discussion, interviews and crosses to newsmakers around the country.”
It is understood to have been developed by Morning Show producer Sarah Stinson.
Obermeder recently co-hosted The Morning Show with Larry Emdur.
“Afternoon television needs a show like this,” she said.
“I’m so excited to be working on a format which will inform, entertain and tell the stories of the day in an easy, accessible style.
“The team behind the scenes is one of the best at this style of fast-paced, live programming.
“The mix of News and Entertainment stories will make for great television.”
While Nine has recently been broadcasting Nine News Now, aimed at female viewers, Seven is yet to declare a timeslot or start date.
