Now, reports have emerged suggesting Nine attempted to secure Sunrise star Matt 'Shirvo' Shirvington for the now-vacant anchor seat, The Daily Telegraph reported on Thursday.

However, the publication alleges Nine failed to tempt the former Olympian after Seven quickly moved to sign him on for a new long-term deal. 

It is believed Nine is now casting its eye internally for a suitable candidate to replace Stefanovic on the flagship breakfast program, with co-host Sarah Abo also set to go on maternity leave in August.

Veteran Nine journalist Steinfort has stepped into the role alongside co-host Abo while Stefanovic remains on leave; however, Stefanovic's disappearance is yet to be addressed by the network.

As speculation mounted online, many fans turned to Nine's social media pages seeking answers.

'Is Karl gone or not? I want an official notice. I will go to morning radio and turn the TV off. Nine is weak if you don't let him speak,' another wrote.

'When are we going to find out about Karl?' a third questioned.

'I'll no longer be watching,' protested a fourth.

Others suggested that Nine should address the elephant in the room rather than ignore it.

'The silence is making everyone speculate,' one viewer commented.

'Just tell us where Karl is. It's not that hard,' added another.

Despite the growing curiosity, Nine made no mention of Stefanovic's absence during Thursday's broadcast.

The presenter has spent more than 25 years at the network and has fronted Today for much of the past two decades, becoming one of Australia's most recognisable media personalities.
