In the groundbreaking announcement made on Monday in Seaford, Searle revealed during the interview process for the position, she and head coach Alan Richardson shared similar philosophies and coaching styles.
"I gave a presentation regarding my philosophies and how I'd go about coaching, and I knew right from that moment we started to connect," Searle said.
"We had the same philisophies and values."
After serving an apprenticeship as an assistant at Port Melbourne under Gary Ayres which she thought may have lead to a step-up to AFL level, Searle wasn't able to immediately realise this dream, but she never wavered in her burning desire to reach the big time.
"I don't think you ever really give up, but it was certainly a time where you take a different direction."
Now she's been offered the opportunity of a lifetime.
"They've [St Kilda] just done a review and there was certainly a hole in the development coach situation," she said.
"Obviously I'm ecstatic."
"I was a bit overwhelmed and lost for words when Alan Richardson first rang me, but it's starting to slowly sink in now and I'm starting to get excited about what needs to be done and actually getting on the track and doing the job."
And doing the job is what Searle believes she does best. She backs her ability, and says it will hold her in good stead as she looks to impress an entire football department.
"I was pretty confident in terms of being myself. You know in footy and in life you've just got to back yourself," she said.
"It's going to be a big change, there's no doubt about that."
Despite the lifestyle change, Searle is aware of the challenges facing the Saints and believes she can immerse herself into a culture that will see great success going forward.
"The proposal was a really good proposal in terms of what I needed to do and what I could bring to the club, and I guess it just really fitted my skill set."
"More so too, just where the list is at – it's such a young list – and for me, it's a great opportunity to come in as a development coach because you can grow and become a part of them and a part of the journey."
Earning the respect of the playing group is one of her biggest challenges, yet it's one she thinks she's already making inroads on, even during her first day on the track.
"I think no matter what you do, you've got to earn your stripes and you've got to earn your respect, and you've got to build relationships, so that certainly takes time," she said.
"Within the morning that I've been here the players have been great, having conversations, talking footy, talking other stuff so I have no doubt that I'll be well received."
A women who certainly loves her footy and backs her skills, also says while she didn't intend to be an advocate for women in football, if that's the way it turns out to be, she'll happily accept it.
"I think that rather than being a crusader for women in football, probably for me it's about being a good role model for my daughter," she said.
"Along the way if that inspires other women, well then that's fantastic.
"It's a testament that if you work hard and persevere and put yourself out there and put yourself out of your comfort zone that no matter whether it's footy or whatever it is in life, that you can achieve things."
In the meantime, if Searle continues to forge on, she may well create even more significant history further down the track.
"I love footy and I think I'm a good coach, and it's always about trying to grow and get better."
"You make the most of what you've got."
She's certainly got her head screwed on, and an enviable attitude to match.
