To find out just who Peter Nevill really is, a quick scroll through the posts on his enlightening Instagram account will unearth what makes Australia's pre-ordained 443rd Test cricketer tick.

There'll you discover insights to his livelihood, his leisure and his loves, from his Baggy Blue cap to his electric guitar to his fiancée of four months, Sam.

Born in the south-eastern Melbourne suburb of Ashburton, Nevill's early childhood memories are all cricket.

An older sister didn't share his passion for the bat and ball game, so with a friendly neighbour as an ally and a nature strip as a venue, Nevill began his journey from boyhood to the Baggy Green.

From ages 7-12, Nevill travelled roughly five kilometres along High Street, up Warrigal Road and down the A29 Highway to play junior cricket for Burwood District Cricket Club, where it became apparent early on that his future lay catching a cricket ball as opposed to bowling one.

During that time Queensland's Ian Healy was the first-choice wicketkeeper for the national team, complementing the likes of Shane Warne, Glenn McGrath and Craig McDermott with aplomb to become an early idol for the budding gloveman.

Closer to home, Nevill was drawn to Victoria's demon behind the stumps Darren Berry, who Nevill describes as a "purist" and the man who influenced his technique and touch throughout his developmental stage.

Nevill's first taste of the real world was more savoury than it was sweet, slavishly taking orders from hungry customers in a Pizza Hut call centre as he attempted to upsell an extra garlic bread or bottle of soft drink in between slices of his favourite cheese and salt pizza.

When it came time to spread his wings and leave the home nest, Nevill followed his father's footsteps in legal practice but only as far as the stationery room where the Bushrangers rookie "strapped himself" to the office photocopier when he wasn't working on his glovework.

Supported by dad, mum and two dogs that are now considered surrogate children, Nevill made the biggest move of his young adult life when travelled north to the harbour city in 2008 to begin an apprenticeship under the man he will replace on Thursday.

After nine seasons without missing a match for his country, Adam Gilchrist's sparkling career ended following the controversial 2007-08 summer against India, opening the door for keeper-elect Brad Haddin before Nevill could finish unpacking his suitcase in his new habitat.

It was with a tinge of irony that Nevill's first-class debut in February 2009 was played against the state he left, at the Melbourne Cricket Ground and in direct competition with Matthew Wade, the man who, like Nevill, had relocated from another team to take the gloves in Victoria.

Nevill doesn't remember much from that game besides a second-innings duck, out lbw to Clint McKay (he made 18 in the first innings) and a routine grab off Aaron Bird for his first dismissal, but he can't forget his best catch to date only a few months later.

Peter met his now fiancée Sam in Sydney around five and half a years ago. Born in Surrey, Sam moved from Melbourne to Sydney, and while she doesn't fully understand the nuances of cricket, Sam is unwavering in the support for her future husband on the many good and few bad days he's encountered behind the stumps.

In fairness to the sturdy right-hander, there's nothing about his stature or demeanour that would suggest a devout following of arguably the greatest heavy metal rock band on the planet, Metallica.

Nevill thrives in a mosh pit as much as he does keeping in the middle, rocking out to his favourite Metallica hit Master of Puppets or Randy Rhodes' body of work with Ozzy Osbourne and Quiet Riot.

More than 10 per cent of his Instagram collection can be attributed to his love of music. Pictures of his axe (guitar, for all the squares out there) and videos of solo jam sessions populate his intriguing selection of snaps.

While his keeping abilities are yet to come under question in his six-year first-class career, it was Nevill's stark improvements with the bat that saw him travel to the Caribbean in 2012 to support Test debutant Wade and cover Haddin who returned home to be with his ill daughter.

The advancement of his game came after a frank self-assessment that his willow work wasn't up to first-class standard, so with the help of current Bangladesh coach Chandika Hathurusingha and England coach Trevor Bayliss, both former NSW mentors, Nevill fine-tuned his technique to become a prolific Sheffield Shield run-scorer and earn his first overseas tour.

In a dressing room in the West Indies, Nevill had one of those "pinch yourself moments", surrounded by modern greats Ricky Ponting, Mike Hussey and skipper Michael Clarke and watching on to see how cricketers at the elite level prepare and train for the rigours of Test cricket.

When Haddin resumed his tenure as Australia's premier keeper, Nevill returned to Shield cricket and built his increasingly impressive CV, winning the four-day competition in 2013-14 with the Blues under Bayliss while also captaining his state with diplomacy and distinction throughout the season.

Part of Nevill's philosophy on life is to stay in the moment and not look too far ahead, but with only one sleep left before he enters the player huddle an hour before play on the hallowed turf of Lord's to be presented a coveted Baggy Green cap, it will be hard for the 29-year-old to resist a peep into the future and dream of his first match in the whites of Australia.

And like his engagement to Sam, his 50th cap for NSW and his copy of Into The Black – The Inside Story of Metallica, there will likely be an Instagram post to remember the momentous occasion.
