Despite leading increasingly busy lives - both run businesses in Banna Avenue and Michella has a young family - they remain as close as ever.

They speak on the phone several times a day, have dinner together at least once a week and help each other through the labyrinth of daily life.

And they're not alone.

A national survey released in conjunction with Monday's International Women's Day revealed one in two women believed their mum was the most influential person in their lives growing up and, when they started their careers and had families, one in five still saw their mum as a key influence in day-to-day decisions.

"We speak every day and it's often for the most trivial thing ... how to cook a certain dish, asking about what we're wearing to work, anything really," Michella, 28, said.

"A lot of it is just about day-to day-stuff like family, food, fashion.

"I still go to mum for advice more than I do anyone else. She's someone who I trust and who knows me so well."

Like many mums and daughters, their relationship has evolved over the years, from bedtime stories to discussing the intricacies of running a small business.

"We have such busy lives but she's still like a friend," Grace said.

"Her brothers are the same. They're both living away from Griffith but they still call me every day.

"I'm still like that with my mum so I guess it runs in the family."
