The Glaswegian pair are from the Celtic Soccer Academy International that boasts 60 partners worldwide in five continents, bar Africa and the Antarctica.
The club, apart from its international and national wings, also has a charity drive on the foundation of its principles dating back to what Irish Marist Brother Walfrid formally constituted at St Mary's church hall on November 6, 1887.
"We've just started coaching camps in China last month," said Murphy who has been mentoring for two years.
But the attitude to work for them is in keeping with the club edict of not just developing footballers but creating individuals who will uphold the values of society.
When he was 15, the former midfielder injured his knees so coaching beckoned.
Having coached for a day at the Napier Marist Club yesterday, he felt children of compatible age were technically on a par with those in Australia.
Several water breaks punctuated their sessions in Australia because of the intense heat. They spent 10 days with the Southerncross Strikers in Cairns, a weekend with Motv8me academy in Canberra and several days with Enfield Rovers in Sydney.
The historic inaugural coaching session between Celtic and Napier Marist started last July.
The coaches employ the 50 "Celtic Turns" structure to encourage players to exude flair on attack and in defence.
They start with eight turns in a day and add more in the week depending on how quickly kids grasp them.
Covering 50 in a week-long trip is not practical but successive coaches over the years will provide continuity.
"We have a connection with Napier Marist so we can also send them the rest of the turns to practise with here."
The skills range varies from novices to those foot-savvy types.
The lifestyle here compared with Scotland, he said, offered Kiwi kids more opportunities to engage in myriad codes.
"The weather here gives you more choices in sports whereas in Scotland we have just football and rugby," said Murphy, adding athletics and swimming were desirable in Scotland but the weather was a deterrent.
"You always find when you come here that kids are more athletic and seem to have more choices but in Scotland they focus on playing just football or just rugby.
"You do get people who play both but not as many," he said, emphasising the club had no qualms about encouraging those who show talent in rugby to pursue a career in a sport that plays second fiddle to the No1 code of football.
Like any elite coach will confess anywhere in the world, the budding Celtic coaches are forever learning.
They may pick up certain attributes from different countries but they never stray from the Celtic philosophy.
"We always have a structure and it's there for us to use even though coaches may have different ways of delivering it."
That structure entails moulding Champions League-quality players.
"We don't want to create players who can only play in Scottish football but we want them to reach the highest level and that's Champions League in Europe," said Murphy, emphasising Celtic were the first British club to win the Champions League.
Within the past two decades the club has produced 19 players who have attained that level from an academy that runs every day of the week for U13s to U17s.
The teens there train from 7am for two hours before attending school and put in a stint after school.
Celtic help fund players' one-to-one tuition as well as other costs such as providing meals and boarding in a country where education is free.
"Education is the most important thing for us at that age because not every player will make it as a footballer ... so they have to have something to fall back on.
"We'll never stop a player from going to develop an education," he says, disclosing the club employs three full-time drivers to cart children to schools daily between training.
Every child in the world has a chance to make it to the Celtic academy but toiling is vital.
"Celtic have scouts all over the place and are constantly looking for the best talent we can find, just like all other clubs do," he said.
The Scottish club boasts nine million fans globally.
"I was in Philadelphia in America and they had three Celtic fan clubs in the same area and all just as big as each other. I went to Panama and there were Celtic tops seen down there."
