The Australian television personality, who has been host of the Seven Network's breakfast show for the past ten years, has allegedly showed interest in an evening TV career after becoming tired of her early morning starts.
A Seven insider told The Sunday Telegraph: "Breakfast's a hard gig and Mel's looking at other options."
Doyle re-signed a contract with the TV network last month for a rumoured $700,000 (£460,000) per year, but had been working "off-contract" for seven months previously, during which time she was apparently "shopped around" to other stations by her agent James Erskine.

A rival television insider said: "We were definitely approached to sign Mel and the whole push was about her moving away from breakfast." At the time, Erskine admitted that he and Doyle had been "looking at opportunities available for [her] post-Sunrise".
Other sources have claimed that Doyle is sick of getting up at 3am and has recently "put her hand up" to work with TV show Sunday Night. Seven boss Peter Meakin, however, has remained coy on the subject.
"She'll be with Sunrise for the foreseeable future but I can't see five years into the future," he said. "Sure we want [her] to do the occasional other thing for the network. But she does one story on Sunday Night and suddenly everyone is running around saying it's a full-time transfer. Well, it's not."
