Melissa Doyle wants to have a word with you about ageing. Yes, you - please sit.

After turning 51 this year, the television presenter - who has hosted a string of shows such asToday Tonight,Sunrise,7NEWSandSunday Night- wants to shine the light on all the women out there who feel like they simply don't exist. All because of their age.

Because in the lead up to her milestone birthday last year, the media icon realised there was a part of her that felt unsettled. Uncertain. Bewildered.

She didn't want to accept all the messages she, and so many other women, were receiving about growing older.

"When you have a milestone birthday coming up - whether it's 21, 40 or 50 - everyone asks, "Well, how do you feel about turning 50? And I wasn't really feeling anything. I hadn't really thought about it. I didn't feel any different to how I felt at 49," Doyle tellsMamamia.

"It started this conversation around what it is about getting older that people feel they need to start asking if you're okay. A lot of different things were associated with this - like, why do we have different perceptions of women? Why does age change how we think about ourselves? Or how others see us as we get older?"

After stepping away from Channel 7 at the end of last year, Doyle is working on some new projects - among them a podcast series calledAge Against the Machine.

Here, Doyle and her co-host Naima Brown examine what it means to get older as a woman by exploring themes such as beauty, dating and careers.

"I decided to start exploring this whole area, and one of the words that kept coming up was 'invisibility'. So many women feel as they get older they are invisible."

"Whether it's because they no longer feel young and pretty or because they're no longer seen as a value in the workplace, whether their role at home has changed - whatever it might be. And we wanted to know, why does this happen to women?"

Doyle tellsMamamiaas you get older there can be a juggling act between your own needs and the needs of those around you.

"We're in that space right now. Our son moved out last year and we've got a daughter in year 12 - but how do you make sure you embrace it and grab it all? It's a really interesting phase."

"They call it the 'sandwich generation' - you're still guiding teenage children into their next phase of life, but also now we're looking after our parents who are getting a little older. You suddenly realise that you need to be looking after them as much as you've been looking after your kids," said Doyle.

And that's not even the half of it, friends. Life over 50 means you also have to somehow navigate your professional life and the societal pressures that come with it - which are not only unrealistic, but unsustainable.

It sounds... exhausting.

Working in the television industry for over 25 years, it's safe to say Doyle has experienced her fair share of pressure and expectations.

"I think for the most part the pressure comes from two places. One, primarily yourself. I think it's a case of a bit of self-pride. I'm not going to walk out of the house not washing my hair after three days and wearing my trackie pants - that's just kind of not who I am."

"But also, the viewers. The viewers are the first ones to comment on your face and say you look tired, or they don't like your hair or they don't like what you're wearing."

"We need to support one another. Let's not make someone's look the first thing you comment on when someone is getting older," said Doyle. "Why do we make that such a focal point? Let's park that."

Here's everything Melissa Doyle wants you to know about making your 50s as powerful as they can be:

1. Focus on the important stuff.

While there's nothing wrong with looking after your skin, Doyle said these days she worries less about the laugh lines around her eyes and instead tries to embrace the stuff that really matters. Stuff that will actually make a difference.

"Yeah, you get a few wrinkles as you get older, yes you get a few little 'arctic blondes' (as my hairdresser calls them) - but that happens - big deal! It's natural. Everyone goes through it," said Doyle.

"Let's talk about the stuff that really matters: how do you maintain a sense of purpose? How do you use your voice? How do we give younger girls of the world support? How do we make sure that they can be mentored and that they can be leaders in their community?"
