Kierran Clarke, Chantelle McGrath, Cathy Ayre and Bronson Romani have all represented Australia before, but this weekend marks a special occasion.
The Newcastle Petanque Club quartet will, for the first time, wear the green and gold sporting uniform on home turf at their Nesca Park headquarters.
They make up one third of the 12-person national open squad ready to host New Zealand in the annual trans-Tasman Test series at The Hill across Saturday and Sunday.
"Being at home [in Newcastle] will definitely be an advantage for us," Clarke said.
Toronto 23-year-old Clarke, who grew up learning the game as a child in France before moving to Australia with his family, arrives at this tournament in form having been crowned the NSW Petanque League shooters champion in Sydney on Sunday.
McGrath, 21 of Blackalls Park, was a member of the Australian team that ended New Zealand's nine-year winning streak at the trans-Tasman encounter in Adelaide in 2017.
Eleebana 17-year-old Romani, whose grandfather John d'Amore was a founding member of the Newcastle club, helped make it back-to-back titles for the Aussies last year in New Zealand.
Now Ayre, 57 of Mayfield, returns to the group four years after her trans-Tasman debut and Australia striving for a third straight crown. She first picked up the sport almost two decades ago.
"I'd bought by husband a set [of boules] for Christmas and then I read an obscure newspaper article in the Newcastle Herald about the club opening up," Ayre said.
This weekend singles, pairs and triples matches, either timed out at one hour or first to 13 points, go towards an overall total. There is also an over-60 division.
